Avie sleeps with us in bed.. and has since she was little.. she has NEVER had an accident in our bed and has ALWAYS told us when she needed to go potty-so we could put her down. she sleeps with us.. but will sometimes wake up and sleep in one of the 3 other beds she has in our room! but then always comes back up.
Gemma will sleep with us if i am watching tv or on the laptop before bed.. or sometimes ill bring her up in the morning.. but she sleeps in her crib, throughout the night!
she's too little and is almost fully potty trained..but i wouldn't trust her to be able to hold it, just in case!
