4 Months Old Baby Development


  Your little bundle of joy is developing a lot of new skills at this age. Probably you can see him rolling and pushing up. He is much more active and social. He will be trying to reach things, he will laugh and play a lot.




The average weight of a 4-month-old baby boy is 15 lbs   7 oz or 7.0 kg and for baby girls 14 lbs   2 oz or 6.4 kg. Probably he gained about 1 to 1.5 pounds the last month, but don’t panic if he isn’t exactly within these frames. As long as he follows a natural, gradual and healthy rate of growth, then he should be just fine.



On average a 4-month-old baby boy will be 25 1/4 in or 63.9 cm and for baby girl 24 1/2 in or 62.1 cm  



The 4-month-old baby tends to sleep 15 hours a day of which 10 hours go to night sleep and 5 hours in total for 2 to 3 naps during the day. At this age and the development of those new skills, your baby could roll over in his crib which increases the chance of SIDS. Observe and if you think your baby is strong enough to lift his head up then occasionally you can let him sleep on his tummy. One more tip. If suddenly your baby stops sleeping during the night as he used to without an apparent reason, it is highly likely to be the 4-month-old sleep regression again. The primary reason for the sleep regression is the development of the baby brain which keeps him more active. Try to get back to the sleep routines and if it doesn’t help seek the advice of other moms, because it will surprise you how creative they get when it comes to soothing their babies. We mentioned it before but will remind you again. Sleep training is good to start after the 4-th month. If you are looking for a sign that your baby is ready for sleep training, there is one. If he doesn’t wake up for feeding at night is a good sign. To read more check out this article 4-month-old baby sleeping schedule 4-month-old baby sleeping schedule checklist



As we said earlier, introducing to solid foods and water should start between 4-th and 6-th month. So now you can start thinking about it and watching for particular signs the baby will give you when he is ready. For example, if you can answer all of the questions underneath then yes, your baby is ready for solids.

Question 1: Can he hold his head up high without getting tired too quickly? As long as he can sit upright with no or little support, he should be good to go.

Questions 2: Is he following your food and does he try to reach and taste it? If he is trying to grab your food while it is moving from your plate to your mouth.

Question 3: Is he trying to do chewing motions? He should be able to move food to the back of his mouth and swallow. Maybe you will notice at that point that he dribbles less. That is due to him becoming more efficient with chewing and swallowing.

Question 4: Has she got good coordination? If he can put the food is mouth by himself, then he is good to go.

First, you should start very slowly to wean your baby from breastfeeding. You can introduce your infant with a bottle or a cup. However, the most suitable choice will be a bottle. Usually, parents start with introducing iron-fortified baby cereals along with the breast milk or formula. Then next suitable choice is vegetables, followed by fruits and meats. Bear in mind this: If you fed your baby primarily with breast milk until now, would be a good idea to start with pureed meat or poultry, as the iron and zinc in those foods are easier absorbable. And as you can guess, make sure all food is pureed and no solids to be put in baby’s bottle. Along with all that breastfeeding should continue to at least 12-month-old or more. For bottle-fed baby’s the amount is around 4 ounces, 4 to 6 times a day and for breastfed babies about every 3 to 4 hours. 4-month-old baby milestones slide





Your 4-month-old baby is developing his depth perception skills. He is now able to determine the object position, size and shape. Along with that his motor skills are improving which allows him to grasp for things like your jewellery or hair. To avoid grasping your hair or necklace, you can introduce him to easy to grasp toy like rattles.



Your baby is now able to reach and touch object as her motor development is improving significantly especially in the arm area. CHECKLIST FOR 4-MONTH-OLD BABY
