If you're using a Hovabator, yeah, I think the sides are high enough. Forgot about that - I prefer my LG and the sides are lower; that's where we ran into problems. We also smooshed one when we put the lid back on; poor little thing couldn't quite make it over the side and we were so busy trying to catch the others that we didn't notice it. That was not a good night...
I wouldn't laugh, nor did I know they even make diaper liners from bamboo! Been a LONG time since my kids were in diapers, so whatever works! (They are 15 and 19).
And the last few days are a killer...that's when I get most of my exercise running up and down the basement steps every few minutes just to peek! Of course when you least expect it, there they are! Oh - and if you see a zipped shell and are waiting for it to come out, start looking. It's already out. They like to "close the door" behind them!
