My daughter has always been extremely tall (she gets it from her momma ). At 6 years 7 months she easily can pass for an 8 or 9 year old. At her last check up, so almost six months ago, she was 54" tall which was off the growth charts and the last time we weighed her I think she was 72 pounds which puts her at around the 97th percentile. She's getting those growing pains in her legs again these days, so she should be having a growth spurt any time now. She is just a really tall, solid girl. The growth chart predicter came out as her adult height being 6'1" (which is what was what the ped predicted when she was an infant).
