Just wanted to ask if any parents out there have moved the LO out of the crib yet, if so...what age and what made you do it? Our LO is 22 months and so far is fine in his crib and hasn't shown any attempts at climbing out or frustration from being in there. BUT our twins will be coming home from the NICU soon and we keep talking about big boy moves and are wondering if we should consider. LO's crib converts into a day bed and then full...so it just takes a screwdriver to make it happen. Thoughts?
