Remind him that a 28 month old is more likely to fall out of a crib than to electricute herself when there are plug covers. I moved my oldest 2 kids to a toddler bed when they were 16 and 24 months(because we had a new baby and needed the crib). My 16 month old will be moved to a toddler bed in Jan, to make room for the next baby. The only problem we had was with my oldest was that one night I left the desitin out and I walked in to find him with it all over his hair!! lol
