The Bumbo.

I have to admit that this horribly named baby seat is one of the coolest thing I've used.  Although I do believe they forgot to add a few things to the advertisement or info about it.  With Anna (when she was a baby) and with Grey, one or more of the following things occur when I stick them in it (which is multiple times a day):

1: excessive burping, or just getting ALL the gas out of their tummy.

2: poop.

3: spit up...everywhere.

4: excessive toots.

I suppose this doesn't happen to all babies, but it seems to help mine if there happens to be a problem in one of those areas.  Grey has been swimming an spit up and/or drool every time I get him out.  Usually both...
