last night he woke up at 2am to go potty(he's got the whining part down)...wanted to play so I put him in the living room and slept on the couch while he played...once I saw he laid down I put him back in the play yard and he slept until 7 this morning. I don't put water in there with him so he doesn't knock it over so usually the last of the water he gets is at 11pm. We wash his bedding nightly in case he did have accidents so it might be when I put the big fuzzy blanket in there that he doesn't get up to wake us up. I should take note when it happens and what bedding is in there. We do have a small bed and working on making different ones...just haven't found one just right yet. Like a mattress store..he has to try them all out
