Rock n play

Any mommies transitioning or have transitioned your babies out of the rock and play for sleep? My son is 13 weeks old and he naps and sleeps in it for night time. He sleeps all night long from 7pm- 7am only waking up one time to eat so I’m super nervous about putting him in a crib for sleep bc I’m afraid he’s not going to sleep well for me anymore and I also have a 2 year old. But it seems like he’s getting too long for the rock and play. If you successfully transitioned out of it how did you do it!?
