Bumbo Baby Seats

No, that's not a typo, I didn't mean to write Dumbo. I'm talking about the colorful, soft, and ever so useful
Bumbo Baby Seat. I bought mine about two years ago and it still looks brand new, despite using it with both of my girls. They come in a variety of colors and cost about $40.
These chairs are great for feeding babies (at least three months old). I also like to use mine as a seat for baby in the bathroom as I get ready or what have you. They help babies build their back muscles so they can sit unaided sooner. Both my girls started sitting up a month earlier than the milestones say they should. I attribute that to using the Bumbo.
The Bumbo is one of the must-have items every new mom should put on her registry or wish list. You can reuse them for every child and because they are super durable you can resell them on eBay or at a local resale shop when you kids outgrown them (though my two year old thinks it's fun to sit in the Bumbo and watch a DVD every once and a while).
Warning: Never leave baby unattended in the Bumbo and don't put the Bumbo on a table or other elevated surface. Babies (especially with skinny legs) can fall out or tip the Bumbo over. These were actually recalled several months ago to add warning stickers that say just that. But there was never a defect in the product, which clearly stated this in its instructions all along.
