The needs and development of your 4 month old baby – Week 16

You should be aware of the following:


Obesity seems to have become a common noun, to be too heavy in adults. There are a lot of health concerns, but fat baby, does not seem to be worrying. Some babies are born fat and others start getting fat when they grow up, but this is not due to an unhealthy diet or lack of exercise, but because the baby is not sufficiently muscular yet and still has to grow up to improve.

If you are concerned that your baby may be too fat, please take your baby for a detailed examination. The doctor will first measure your height and weight before comparing it to your child of the same age. If your baby is too heavy, your doctor will check your child’s development. Physicians don’t pay much attention to the weight of your baby at this stage, especially if they have not start eating solid food yet.

A fat baby does not mean that they will grow up as a fat adult. Many babies start to climb or walk, lean down, and as the baby grows older, you can encourage the baby to play more on the ground. Only give your baby milk when he or she is in the hungry. Do not rely on a “kiss-feeding” to soothe and comfort the baby as this will truly lead to unnecessary weight gain.

Don’t overplay.

When you throw your baby into the air repeatedly, your baby will look very excited and seemingly having a fun time. However, such move is dangerous, and some games are not suitable for babies under 2 years of age and they might be injured by excessive shaking during throwing. The baby’s head weight is almost as much their entire body, and the neck muscles are not fully developed, so the support of the head is weak. When shaking, the head tilts, which can cause brain collisions with the skull, swelling, bleeding, stress or damage to the optic nerve, resulting in life-long mental or physical effects.

This can also cause eye damage, if the retina is stripped, the optic nerve will be affected and the baby’s vision will be impaired and even blind. Therefore, avoid overplaying the area of their head while playing with your baby, and support your baby’s head and neck with your hands, and avoid jogging or bouncing. The above warning does not mean you cannot play with your baby. Instead, play gently, putting your baby’s safety first.

Reminder for parents

The following are things that you might notice:

The baby’s still using the pacifier.

There are things that soothe your baby, like sucking of a pacifier, singing lullaby, or feeding on nipples which can get them addicted. So, if you want to avoid their over-reliance on these things, it is now the perfect time to reduce their usage. At this stage, baby’s memory is limited and will soon forget about the existence of pacifiers. The reason why it is recommended to quit the pacifier at this point is that babies at this stage are more able to adapt to changes than later on, and this can also make it easy for them to quit nipple.

To make baby comfortable without pacifier, gently shake the cradle, sing a lullaby, or let baby suck their sleeve (or suck their hand). If your baby isn’t ready have their pacifier taken, you can start by reducing their usage time, or use it only when taking a nap or to put your baby to sleep at night.

Early Breast

In general, baby’s first 3 months of life is very comfortable and easy to adapt to the environment. If you think it’s time to wean your baby, do it. Even if your baby likes to feed it, it’s easier to wean your baby now than at 6 months of age. If you want to break this habit early, you can let your baby drink formula and mix it into your milk for 4 to 6 weeks. You may try different ways to see which one your baby likes most, and at this stage it’s best to formula your baby and reduce your mother’s milk. Do not quit, remember, consistency is the key.

Try the bottle before feeding. If your baby refuses the bottle for the first time, try again next time.You should keep trying until your baby can drink 30 to 60 ml of milk from the bottle at once. If your baby is already able to do this, try replacing it with formula and slowly increase the amount of formula after a few days. Take it slowly so that your chest can slowly adapt to the secretion of milk. You should not spend more time on feeding at night, so your baby will have a quiet time to rest with you after work.
