3 month old not sleeping

Laura

Hello my son is going to be 3 months next week and he's not getting enough sleep. He'll get like 20 minutes naps and about roughly 6 hours at night. He has eczema, I've been treating that. Called his doctor and waiting til next week to see him. I've walked, swaddled, unswaddled, drove and just about almost everything. He's like this for a week. Any advice to keep him asleep at least until I see his doctor. Please help.
