I've never used a crib tent myself - too expensive. About a month after I posted my original post, we set up the toddler bed and took down the crib. My son is now 25 mos old. He manages to fall out of the bed on occasion, so we have an old crib mattress next to the bed - during the day, we slide it under his bed.
My son climbs on the dresser, too. Our blinds are all bent up because of him playing with them. I've given up trying to protect him. There have been a few things that he's gotten into (clean steak knives in the dishwasher) that have hurt him mildly, and he's learned real quick not to repeat those actions. But, his balance is amazingly good. He's been climbing on tables since he could walk, but doesn't do it as much now.
Today, my toddler had a fever. He woke with it yesterday, and today he still has it, along with diarrhea. But, he is bound and determined to potty train himself! I have him in a diaper today, but he keeps taking it off and telling me he has to pee. Sure enough, he goes when I put him on the potty. He had only one small 'leak' accident yesterday, and none today. (It's his bowels we had problems with today!)
I wish all my children had been this easy. But, then again, he is much more difficult in other aspects, so I guess this is God's way of helping me.
