Hi K.. Congrats on new baby! I have 2 sons (23 months apart) when oldest was 18 months he switched to a toddler bed, in anticipation of new baby. Did great, stayed in it, no issues. Then when new baby came he started getting out of bed. We took the bedframe away and put the mattress on the floor and he LOVES IT! No worries about falling out of bed and I can sit by him if he needs a little comforting. If I had to do it again I would get a single mattress and leave it on the floor. Just my story. Good luck!
