My mommie bought me a rocking snail from Costco yesterday...the only problem is, it's too small already and I can't even use it yet since I can't sit by myself! The seat is not adjustable, and as it is, my big butt can barely fit in the seat. I don't know how it's for 9 months-3 years old. So back to Costco it's going to go... My mommie can let go. My butt is wedged in so tightly that I have nowhere to fall to~!!!!
