12 week old sleeping so much

Joyce

Anyone else's 12 week old sleeping extra like pretty much all day? He is 12 weeks as of yesterday and that's when it started I read about a 12 week growth spurt and wondering if that's what it is. No fever or anything else 🤔 my first is going to be 4 on Thursday and I can't remember if she went through this I do know she slept more for a day or two during growth spurts but I don't remember if it was this much
