Have any of you ever put thicker soled shoes on your not quite 40" tall child to get them past that 40" mark? My younger dd is like 39 3/4" tall with the shoes that she wears every day (timberland sandals). BUT... she also has flip flops that have a really thick sole, which puts her above the 40" mark. I'd just swap her shoes right before getting in line. Think they'd let her go?
