Anyone think their baby started the "4 month sleep regression" a little early? My son is 14 weeks this week. He was sleeping from 7:30pm to 7am... Up until this past week. Now, he's getting up at midnight and 3am too. He'll be kicking in his bassinet, I'll feed him for about 20 minutes, then he's easily back to sleep. It's not the worst but I guess I got used to my uninterrupted sleep! I'm just trying to figure out what may be going on here. Thanks!
