I have been reading all of these threads about toddlers and rides. And from what I have seen most kids aren't 40 inches untill they are 4??? My DD will be three in a few weeks and is already at 40 inches!? I am hoping I am not going to have weird looks at the gate when I tell them she is two. I just really never thought about it till now. Is there anything I can bring to set my mind at ease? It's not like she has a drivers license LOL!
