4 months old and wants to still be a newborn lol

Ni

He has rolled before.. one day he was obsessed with rolling.. but now he absolutely refuses to roll either way?! He also still wants to sleep in my arms.. all night.. I feel like he’s a forever newborn. Has anyone else started sleep training? How has it gone? We are currently living with my mom while we build a house so our sleeping situation isn’t great.. But I kind of want to sleep train so he learns to sleep on his own, but I don’t want to cut out night feeds. I sleep trained my first at 4 months so I honestly don’t know what I’m looking for by posting this. 😂 maybe just the comfort of knowing other people are going through it along with me? Lol
