Hi my dd is 22 mo and seems to be very tired at the moment. She is starting to fall asleep an hour before bed time and has been in bed early all week because of this. She has been having her usual day time nap and she is sleeping brilliant overnight as she would normally. She is also waking later than usual. She is her normal self other than this. Is it just a growth spurt or should I get her checked out? Thanks for reading Limy
