RE: bumper pads foam or batting (sp???)-hand made...
I made my sister's bedding and used batting for the bumpers. I think all bumpers have batting in them - I cannot say I've ever seen one with foam in it. I would think it would be way too stiff and you would almost need ties for each post to keep it curved around your round crib. Foam MIGHT work on a standard crib, but I don't think it would work at all on a round one. Batting also 'crumples' when you press on it (at least the thinner kind you're supposed to use in bumpers), so your little guy shouldn't be able to get much of a foothold on it. Foam, on the other hand, is springy and might actually help catapult him out. I want to say I read on these boards that Hancock's or JoAnn's Fabrics carries batting specifically for bumpers - you may want to check those out.
On a side note - DEFINITELY get foam for the toy box cushion. I'm working on one for our nursery (as well as basket liners for under the changing table, Roman shades for the windows, and knitting a baby blanket - all talents courtesy of my grandmother!) and batting would flatten after a couple of sittings. You may, however, want to request the foam be wrapped with batting for the cushion to make it look more plush. I'm also putting elastic on the corners rather than velcro on the bottom of the cushion and top of the box - when Aidan has outgrown his nursery, we can just take the cushion off without damaging the box. There's also a zipper on the back so if we want to change the theme (DH wants baseball when Aidan moves to a toddler bed) we just have to take the cover off and replace with a new one. HTH!
