okay ladies my son will be 8 months when his dad gets back should I just get him a toddler bed or should I get him a crib like I planned to but the crib I want turns into a full size bed later but I'm worried he might roll off while he sleeps because he's a crazy sleeper . idk what to do . but the first month he's going to be sleeping in his play pen/ with me and daddy till he adjust to our new home
