My baby is 20 days old. From past 2 days she has been very finicky in having milk, doesn’t sleep much like she used to sleep properly earlier. I have seen her very active from 2 days, she doesn’t even want to remain in the swaddle wrap and just wants to open up and play... What could be the reason she isn’t having milk and sleep properly ?? What is the overall time a 20 days old should sleep in a day? What is the time they should play ?
