So I've always wanted to keep my little one next to me in his bassinet until he was 6 months but he quite likes the space he has in his crib

The crib is in another room that adjoins to mine and I can see him from where I sleep, I think he will sleep great but it's just me that's holding back as he's 4 months and I like the reassurance of him being next to me

Should I just quit being silly and go ahead and make the move or wait it out a little longer?
