My baby is 8 weeks old and is normally a pretty good sleeper throughout the night. He still wakes up 3 times to feed but normally sleeps well in between. Last night he would not sleep at all... from midnight until 9 am. He was kicking and flailing his arms... cooing, whining and grunting. He was just wide awake and we could not calm him down. Today he has had one nap but that’s it. He is eating normally, peeing and pooping. Anything to worry about or is this normal for this age??
