any advice for leap 4?

My lo is 13 weeks and 3 days and I'm dreading leap 4! It seems like he goes through leaps a few days earlier than what the app says. This last leap was easy during the day but waking up so much at night. Now he wakes up around 1 am and again around 4:30-5am. I don't know how I'm going to handle leap 4.. how's everyone else doing??
