Doesn't make any sense to me either. I think its strange that she is 44 inches tall and weighs 44 lbs.
The average height for a 6 y/o female is about 43 lbs. The average height is around 45 lbs (at least at the 50th percentile). Personally I wouldn't necessarily know an exact height or weight for my kids at that age... I might remember their last pediatrician's appointment stats, but those could be several months old.
