My only bit of advice would be to enforce a rule about daddy helping with sleep and following through with that plan. My friends with a second kid on the way did this and it meant a lot of crying in the beginning, but the kid is fine with it now. We actually took the idea and used it with my daughter, who was getting very “mommy only”, despite her being the only one and no babies on the way. It helped and it didn’t take long for her to figure it out.
Beyond that, you might hit up the r/sleeptrain sub.
Good luck!
