We transitioned LO to a toddler bed (just took the railings off her crib since its a convertible) a few weeks ago. The first week went fine, but then she started coming into our room in the middle of the night to cuddle because she said she was scared.
We tried a few things (different kinds of night lights mostly) and then just started bringing her back to her room immediately when she came into our room.
I'll be honest. It was hard to do this because I liked the snuggles! LO and DH are not very snuggly people, so that was the first time we've ever slept/snuggled together since she was a tiny baby. The hardest part was giving up the snuggles, ha! But we all sleep better with our own space.
She's been staying in her room all night the last week (found a good nightlight she likes) so I think this phase is over for now.
