So my 7 month old for the last 2 days has been taking his bottle before bed BUT instead of going to sleep like he normally does (8:00-8:30) he’s not going to bed till 11! He takes his naps during the day and feeds well. But he is teething and has had a cold (idk if any of that is the cause of it) My concern is that since he’s taking his bottle so early and falling asleep later he’s waking up way too early because he’s hungry. He normally would hit 10 hours but last night when he fell asleep till this morning he only hit 8 1/2. Has anyone gone through this? Is this considered sleep regression.

He also has been only wanting to nap in my arms and will wake up when I put him down.
