Hi, I have heard from many doctors that we should feed babies as per demand and not necessarily in particular schedules. So I wanna know if this is applicable to all the babies or only to particular ones??? My son is 3.5 months old and we usually feed him every 1 or 2 hrs because if we follow the above formula he won't take the feed then. Because he will play continuously for hours without feed and sleep, then will become cranky to handle. So what actually should be followed to maintain the increasing weight and feeding well??
