Toddler Seat

C.,
Both of my children weigh well below average for their ages, so I have done my research on the carseat issue. I recommend a seat by Britax. I have not looked lately, but I believe they have a seat that starts at 30 lbs. The Marathon model comes to mind. At any rate, I think you will find what you need by looking at Britax convertible seats rather than for a traditional booster seat. Good luck.

I found one that I think is awesome. It's a Compass. It is very easy to use. My daughter is very tiny and she fits into this one pretty good. It also folds. You can get it at Toys R Us, Babies R Us or www.onestepahead.com

Hi C.-
There are seats out there for 30lbs and up (backless booster). I found mine at Target. I found it while going through the Sunday Shopping Ads...I believe it's an Evenflo. I still would prefer getting the convertable seat that you can make backless when you feel it's the right time, but I haven't purchased one yet. The reason I say that is because there have been times where he has wiggled out of it....but thank goodness, it's been when we were in a parking lot.

Hope this helps!

Both Combi and Cosco make a booster that starts at 33 or 30 pounds respectively. Good luck!
