My baby is 4 months old and is showing different patterns of feeding and sleeping since last few days. She is not drinking milk when she is hungry, rather keeps finger in her mouth. And when I feed from bottle, she is not taking like how a hungry baby should. She is bottle fed. Also, we have to make her drowsy to feed her. once she is drowsy, she drinks. Anyone else observed such behaviour with their kid? I'm worried as she is not drinking enough nor sleeping properly.
