Does anyone know why my 7 week old (almost 8 weeks) likes to arch his back? 1- When he's about to wake up, he'll arch and twist and turn (can last at least 5 mins). Then stretch arms/legs
2- When we put him down for a nap he'll do this (but stay awake - how do I get him to sleep? He's swaddled and everything!).
3- After feeding, he'll arch his back and then stretch arms/legs
I thought it was cute, but now i'm wondering why he does this.
