My son is about to be 4 months and for the past 2 weeks he has been sleeping horribly. Before he had just begun to sleep 6-8 hours straight through after going to bed around 8-9 pm. Now he gets up every 2-3 hours again and wants to drink a bottle every single time. He is drinking more ounces as well. Is this sleep regression? Growth spurt? I feel like I have a newborn again because I am barely getting any sleep!! When does this usually let up? Any tips on how to help him sleep better?

He usually sleeps in a rock and play and I’m trying to slowly transition him to his crib. We have a good night time routine in place and none of it has changed so I’m not sure what to do.
