Your Baby Development: 4 Weeks OldHow big is your baby? This week your baby will be weighing around 9 pounds and measuring 21 inches if he/she was of average size at birth. At this stage you may notice that baby’s bowel movements begin to fall into a regular pattern, and he/she should be passing one or two stools per day. His/Her grasp reflex is also developing and he/she may briefly hold onto anything you place in his/her hand. Head movements are also improving with baby being able to move his/her head from side to side to follow an object. Baby may be able to lift his/her head enough to clear beneath him/her, even if it may take as long as 30 seconds to do so. He/She may even be able to briefly hold his/her head up when lying on his/her stomach. You will also notice that baby is getting more mobile and now kick his/her legs in the air. This is why it is so important not to leave him/her alone when one the changing table, or any other surface from which baby could fall. Failure to Thrive If your baby has not gained enough weight to reach his/her birth weight by this stage then your pediatrician may become concerned. He may also become concerned if your baby gains weight and then suddenly stops for no apparent reason. What can you do if this is the case? Trying to get your baby to take in more when he/she does feed or trying to get him/her to feed more often is one way. If your baby is not getting enough milk from feeding, then you may be advised to offer a supplementary feed with formula milk. Your pediatrician will be able to advise you on this matter if you are concerned that your baby is not developing and growing as he/she should be.
