Hello parents My youngest is currently in child care for abt 1.5 weeks. Somehow he kept on crying when its time to sleep. According to the teacher he didnt finish his food and slept for 20 mins only. Woke up crying and he refused to drink ebm ??? My youngest has been direct latch since birth and rarely bottle fed. I will be starting work soon and very worried about his well being. This is my first time encounter such experience as my other children are able to adapt very well. Any tips on this?
