They get away with more if they stay little and cute LOL.
DD2 has been going to gymnastics with DD1 and they all think she is SO cute. Especially when their new leotards arrived and she started wearing it.
There was one day after going there for months that one of the coaches says to DD2 oh, thats ok you don't have to do this you can do such and such instead. Then DD1 turns around and says "she will be 9 in 5 months" The coach and a few of the girls were all like no way! LOL Then the coach was like really, then get back here LOL. They all thought she was no older than 6.
