DD is 6 weeks and we've been swaddling her but she seems hot when I wake up to nurse her. She's not sweaty, but the back of her neck is really, really warm. We have AC but our room on the third floor tends to be warm. I sleep with tank/shorts and no blanket even with the AC on so I'm guessing she has to be hot all swaddled up. She wears a onsie underneath. I want to ditch the swaddle but I think she does sleep a little better with it. Do you swaddle your summer baby? Do they get hot?
