Hi Kristy!
I *LOVE* the walker my son uses! It has been SO DURABLE! (I have fallen and landed on it....twice, with my son in my arms, and has gone right back to perfect each time!) It's made by Kolcraft, and the cool thing is that it doubles as not only a walker they can sit in, but, you can reconfigure it so your child can stand behind and push it! It has music, a steering wheel, the musical part is removeable, and reveals a place where you can put crackers or fresh pieces of fruit (or whatever!). It's called the Tiny Steps 2 N 1 Walker. We bought ours at BabysRus....my son weighs 27 lbs and STILL loves chilling in there, even though he walks! Good luck!

BTW, this walker is STURDY, my little dude NEVER tipped it over.
We also had the Bumbo (he out grew it months ago) and it's a great item, but not (in my opinion!) as a replacement for a walker. More as a replacement for a high chair, or something to that effect. It lacks any toys, but, has a very high resale value on eBay. (Our Bumbo cost $40 new, and I sold it used on eBay for $36!)
