6 week old suddenly sleeping 6-7 hours a night - normal? Or regression?
At 5 weeks 5 days, after a long weekend staying with family, my now 6 week baby boy surprised us by knocking out from 12am-5am Sunday evening, 12am-6am Monday and Tuesday evening, and last night he slept from 11:45-7am. I recently upped his formula intake from 4oz every 2 hours to 5oz every 2-3 hours or whenever he’s hungry (yesterday he cluster fed 2oz every hour before bed) and he would either finish the bottle or leave half to a quarter in the bottle.
Since he was born he’s only ever given us 2-3 hour stretches if we’re lucky. Normally it was every 2 hours since birth on the dot he’d wake up crying & hungry and my husband would make the bottle and I’d feed him.
Baby has regained his birth weight and then some. He was born almost 3.9kg / 8.7lbs. So he was a chonkster. He now at 6 weeks weighs 5.6kg / 12.3lbs. Hence why I upped his intake from 4oz to 5oz.
Part of me thinks his body is adjusting well to the new 5oz and he’s not as starving for his growing body like before. The irrational part of me thinks something may be terribly wrong…
He is wetting diapers 5-8 times a day and doing a good poop once a day, so he’s not showing any warning signs. He naps whenever I put him down in his Najell carrier or his bassinet only after a feed and burp. He would just close his eyes, milk drunk, and have a nap. Or he would nap on me, which he finds the most comfortable. So nothing out of the ordinary. We had his blood work done a few weeks ago and everything came back normal, no bacteria in blood etc. He also has grown out of his newborn and up to 1 month clothes almost overnight also, and he’s now in 0-3, however they’re getting quite tight almost every day.
I’ve also noticed over the last weekend that he has way more energy than before. He’s flailing his arms and legs and looking around the room, tracking me and others as they walk past him and behind him. He’s become way more aware of people & life around him. If we have conversations with him he will babble and squeal in baby replies, which again has never happened before and I feel like it’s been unlocked this weekend when my mother was talking to him constantly. It maybe unlocked a new feature of his I feel!
Has anyone else experienced this sudden literal overnight change in sleep? Does anyone know why this happens? Is he going through another growth spurt?
He wears an Owlet monitor to sleep every night, which eases my anxiety. Will this sleep last, or am I supposed to wait until he’s back to waking every 2-3 hours starving?
