#bed

We are switching from crib to bed and it's not going well. Help!

We are on day 9 (feels like 900) of my sons sleep journey. We started with the book at bedtime and whenever he asked, which was often, removed his crib, set up his room and he was excited. For two nights it was perfect. He just went to sleep for naps and bedtime no issues. Then the novelty wore off for him and it sunk in.
We are going in 4-6 times a night and I am exhausted and dad is slammed with work, he needs to function; we both do. What do we do about this looooong ‘go to sleep’ time?
