Our friends are going to join us on an upcoming visit to DLR, and it's going to be their first trip (yay!) Their DS is 2, and will turn 3 about 2 months after the visit. But...he is huge. Gigantic. He is off the charts in both height and weight, but he is 2 years old. Do you think the parents need to bring a birth certificate with them to prove their DS is not yet 3 years old? They would prefer not to have to bring it and take the chance of it getting lost, but they will if they have to. I've never had this problem since my DS is tiny for his age, so I'm not sure what advice to offer our friends. Has anyone ever been asked to prove the age of his/her child? Thanks!
