Week by Week

What do you need to know to care for your 11 week old baby?


Development & Behavior

How should my baby be developing?

The baby’s movements will become more smoothly. You’ll recognize that the movements of your baby’s arm and leg are changing more and more complex due to learning through observing others. These movements can help them strengthen and develop muscles. When lying, they will start pushing legs out more. This is the first step for your baby to prepare learning to crawl.

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

  • Keep their head steady when keeping upright;
  • When lying, they can lift the chest up by hands;
  • Turn the ring (in one direction);
  • Grab toy rattles;
  • Focus on small items such as dried grapes (but make sure you do not let the small things easily cause choking in their reach);
  • Reach out to objects;
  • Say the words with almost identical consonants.

How to support my baby?

Give your baby enough space so they can straighten their body and move limbs. You can also put a blanket on the floor and let them move arbitrarily, this will help them to strengthen and develop muscles.

Health & Safety

What should I discuss with my doctor?

Depending on the specific situation of a child, overall physical tests, as well as the number and type of diagnostic techniques and procedures for implementation will be very different.

The changes concern

If your child has concern changes in temperament, taste or your baby has undigested food, high fever, loose abnormal dung, dripping and little urine, persistent rashes, eye or ear discharge, prolonged abnormal cry, it may be a sign that your child is sick. Let’s take them to the doctor immediately if your child has trouble in breathing, or convulsions.


If your baby has a fever, remember that fever is the body’s way of reacting to encounter invading bacteria and is a positive sign, not just the disease. When you call a doctor, be calm and make the detailed description of the symptoms. You should also tell your doctor when the baby began to fever, how long it lasted, if it comes with any abnormalities or not, such as teething. You should also let your doctor know if they had been with sick people and temperature for the baby before calling the doctor. You should also tell your doctor know if your child has been using drugs or not.

What should I know?

Here are some things you should know about:

Seborrheic Dermatitis on Scalp

This is a type of dermatitis in the scalp which is common in young children. Mild dermatitis can be treated by massage with mineral oil or lubricating oil to make the scalp relax, accompanied by thorough washing to remove dandruff and sebum. The more severe cases, such as flaking scalp, sulfur antiseborrheic shampoos containing salicylate may be used daily. However, you should note that some cases may become worse when using this method. If the baby’s condition becomes more serious, stop any treatments you are applying and talk with your doctor to find other treatments.

Seborrheic dermatitis on scalp becomes severe if the baby scalp sweats, so you should keep your baby’s head always clear and dry and should not wear a hat for the baby if not necessary.

When seborrheic dermatitis on scalp becomes severe, the stain will spread on the face, neck or buttocks of yourbaby. If it happens, the doctor may also prescribe topical ointments. Sometimes, children will suffer seborrheic dermatitis for a first year, in some cases, the baby’s illness may last longer. If the disease does not cause unpleasant sensations for the baby, you should not use these treatments or any specific allergic skin topical medications. However, you should talk to your doctor if you have any additional questions.

Leg curl

Most babies legs were curled up. This occurs by two reasons. First, children are bent right leg when they were born. Second, the cramp in the uterus of the mother often makes baby legs squeezed together to reverse. After months in the squeezed position, your baby’s feet will bend or rotate inward. In the following months, when your baby’s legs are free, they learn to leg up, crawl, and then back, and their legs will start to straighten out.

Most of the baby foot will return to normal condition without treatment. You just need to make sure that no other cause can makes your baby’s legs bent. Talk to a doctor in time to take the exam. You should also pay attention to your baby regularly to check the development of your baby’s feet.

Testicular shrinkage

Sex organs in your baby usually start developing during pregnancy. While the ovaries finish developing at birth, the testicles will finish developing by dropping down at the base during this month. But in fact, there are about 3-4% of full-term births and 30% of the premature baby with testicular shrinkage. The shift of relatively complex testicles iseasy for you to determine the baby’s testicles which have shrunk or not. Normally, the testicles protruding from the body when he suffered extreme temperatures (this is a mechanism to protect the sperm when temperature is too high), but it will shrink when the temperature is lowered slowly (this mechanism helps protect sperm when temperature is too low). Some boys have testicles which are particularly sensitive and are often located deep in the body. Most of the left testicle is usually lower than the right and it makes the right testicle seemto disappear. Therefore, you can only diagnose if the baby’s testicles are shrinking when one or both testicles are not visible in the scrotum even when your child take a warm bath.

Testicular shrinkage does not cause pain or urinary retention. Typically, they will stretch. At one-year-old baby, only three to four babies out of a thousand boys live with testicular shrinkage. Surgery can easily put the baby’s testicles back to the appropriate location. Hormone therapy can also treat this case, but the likelihood of success of this approach is not high.

My Concerns

What I am concerned about?

Here are some things you may be concerned about:

Baby talks

The baby still can not talk or answer you at this time. However, your child will learn to talk faster and better if you try talking to your baby from the beginning. If they never have talked to other people, this may not affect the language skills but also may cause your child to suffer the problems of growth, however, this case is very rare . You can teach them to say anytime at anywhere, such as while you are cuddling baby, soothe when your baby’s crying, tell them that: “It’s time to take a walk.” “Oh no, there’s the phone now.” When theyhear you talking to someone else and when you talk to your baby, your baby’s language skills will grow up a lot.

Breast feeding on one nipple

If you usually breastfeed on one nipple, such as left nipple, let your right hand can be used to eat, hold a book or listen to your phone or handle other tasks, your right breast will be limited in size and secrete milk. One side will have much breast milk as you’re often feeding on that nipple from the start, this will help stimulate the lactation. In many cases, after lactation, the mother’s chest will be in the condition that one side’s small and the other’s bigger(although only you can see). However, please rest assured, the size difference will be improved after weaning your baby.
