My almost 4 month old has always been a star sleeper! She’s in bed my 10pm and wakes up around 9am for her first feeding. Over the past week she’s completely stopped crying for food! She’ll still wake up around the same time but she would lay in her crib for hours just playing and kicking but no crying at all. Today i slept until 12:30pm! She never cried! Is this normal or am i overreacting? She’s never been a crier for wet or dirty diapers but she usually cries when she’s hungry. What’s going on? Any ideas?
