Development & Behavior

How should my baby be developing?

Your baby is now at ninth week . Your baby can tell the difference between familiar voices and other sounds, and they are becoming a better listener. They can also show you that they are in tune with their environment. Notice how they look to see where certain noises are coming from.

An ongoing conversation can help your baby develop their sense of place. They may even watch your mouth as you talk or be fascinated by how it all works. You’ll be amazed by their ability to communicate with a growing repertory of coos (musical, vowel-like sounds), smiles, and unique cries to express their different needs.

In the first week of the second month, your baby may:

  • Smile in return when you smile;
  • Distinguish the difference between familiar voices and other sounds;
  • Start to look into where the noise comes;
  • Reconcile with surroundings better;
  • React to a bell in many different ways, such as staring, crying or keeping silent.

How to support my child?

Your can support your baby by having an on-going conversation with your baby. It may seem like you are having a conversation with yourself but it will help your baby’s cognitive development. They can learn by the movements of your mouth and your expressions and excitement in your voice. You will be surprised by your baby’s ability to communicate by speaking back with gurgling sound creation, laughing or crying to express different needs.

Health & Safety

What should I discuss with my doctor?

Depending on the condition of the baby, the number and type of technical evaluation and implementation procedures will be very different. But you can anticipate and consult with your doctor about the following issues:

  • Your doctor will check weight, height and head size of the baby to make sure the baby is growing at the appropriate speed.
  • Check sight, hearing, heart and lungs of the baby, check baby from head to foot, chest and back, ensure your baby is healthy and can achieve development milestones.
  • Let your child get some following vaccines: hepatitis B, polio; diphtheria, tetanus and pertussis, hepatitis, pneumococcal, ear infections and meningitis; diarrhea caused by Rotavirus (oral exposure) to prevent common causes leading to severe diarrhea.

What should I know?

Here are some things you should know about:

Vaccinations

Many parents probably heard a lot about the risks rather than the benefits that vaccination brings. But the doctor will confirm with you that for most infants, vaccination is beneficial because vaccination will keep your baby safe from diseases that easily encounter.

Immunization activities based on the following mechanism: when we come into contact with weakened/dead pathogenic microorganisms or be exposed to hazardous substances that have become harmless after heat treatment or processing chemistry, the body will produce antibodies. These antibodies will develop if your baby’sbody is infected. They are equipped with a special memory of the immune system to recognize and kill specific microbes if they attack the body in the future.

Although immunization has saved thousands of children every year , this type of prevention is still not perfect. Most children can have little mild reactions to the vaccine, some children become sick, in some cases it can become very serious disease. Some vaccines in rare cases also cause permanent damage or even death in newborns. To limit risk, you should refer and apply some precautions below to ensure that your baby has safe vaccination:

  • Make sure the doctor has thoroughly checked the baby’s health before vaccination to reassure that your baby does not have a serious illness. You should delay vaccination for the baby if the baby is ill. However, when baby has minor illnesses such as colds, you do not need to defer vaccination.
  • Please read information about the vaccine that doctors give you before vaccinating your infants.
  • Watch your baby carefully for 72 hours after immunization (especially in the first 48 hours) and immediately inform the doctor if they have any serious reactions or unusual behavior. Also you need to press the matter of your child’s serious reactions to the doctor inyour next visit.
  • Ask your doctor the name of the manufacturer of vaccines and vaccine batch / the number in the records of baby’s reaction. Keep a copy of this information. Serious reactions of the baby will be reported to superiors by the doctors to get timely treatment direction.
  • Before the next vaccination, repeat for physicians to remember the baby’s reaction to previous injections.
  • If you have any concerns about the safety of vaccines, talk directly to the doctor.

Although there are very rare cases of babies with severe reactions after vaccination, you should call your doctor if your child has any of the following signs within two days after vaccination:

  • High fever over 40 ° C;
  • Crying lasted more than three hours;
  • Epilepsy/seizure although this symptom is normal and does not causes severe febrile;
  • Epilepsy or abnormal behavior within seven days after injection;
  • Allergy (swelling of the mouth, face, or throat; difficulty breathing; hives immediately);
  • Listless, slow response, excessive sleepiness.

If your baby has one of these symptoms after vaccination, please take them to a doctor and collect and evaluate this information in order to help minimize risk in the future.

My Concerns

What I am concerned about?

Here are some things you may be concerned about:

Bottle feeding

Some mothers can bottle feed to their child  in order to get free in afternoon or evening occasionally. The reason may be that they have to work back or their child has slow weight gain if their babies just only has breast milk.

Whether you are planning to bottle feed regularly, squeeze and refrigerate six bottle of mothers’ milk to prevent the unexpected case. This will give your baby a stock pile milk when you are sick, when oral medication might affect your breast milk or you can work urgently to go away for a few days. Do not worry if your child has never been bottle-fed by breast milk, the similar taste will help your baby bottle fed more easily.

Some children do not encounter any difficulty in the transition from breastfeeding to bottle-feeding and vice versa. But most children will adapt better if you extend the time to breastfeed for three weeks, preferably in the first week of the baby. The early bottle feeding may impede breastfeeding because your baby can confuse the breast and nipple. Another reason is breastfeeding and bottle feeding require different techniques. However, if your child is bottle fed later than this time, many babies will refuse a bottle as they are familiar with breastfeeding.

Breastfeeding is very comfortable at one point that you will breastfeed when your baby wants without considering how much milk that your baby drinks. So as soon as you start bottle feeding, the first hurdle is determining the amount of milk that your baby needs. You should consult with a doctor or nutritionist in this case, because each baby in each age group will have different nutrient needs.

If your work forces you to miss two times that you should breastfeed your baby, switch to bottle feeding. You should start bottle feeding at least two weeks before returning to work. Give your baby a week to get used to feeding a bottle each day before switching to nursing two bottle per day. This will not only help them but also your body gradually adapt to change if you intend to let your baby have supplement formula. Your milk supply will decrease and will help you feel more comfortable to return to work.

If you intend to bottle feed your baby occasionally, cleanly squeezing on both sides of breast milk before let it out will reduce the problem of engorged and leaking milk. Make sure your baby is not fed too closely to the time you come back because you can breastfeed when you got home if you are full of milk at that time.

Baby’s first smile

If your child does not smile at you, do not worry. Even the happiest child will not really laugh until they are six or seven weeks. And when they began to smile, they just laughed randomly. You will be able to distinguish their real smile with random smile by observing how they use the whole face to smile, not only using the mouth. Although they does not really laugh until they are ready, they will laugh with you sooner if you talk to them, play and cuddle with them more.
