We have had this crib for 9 years. We are now done with it. Marley didn't sleep in it too long. She liked sleeping with her Mommy too much! Hunter started climbing out of it when he was 2 years old. Jenna will be three in March and we finally just had to kick her out so that we could make room for a Christmas present that was coming! She is now sleeping on the bottom bunk under Marley.
