Charlie started out chubby and tall when he was born, but now he is short and thin alas. I believe ~25th percentile for both, but probably lower. He hasn't gained any weight in a very long time, and I don't think he will be very tall given that he is the shortest child in his daycare (though not the youngest).
Olive is thin and tall so far. 75th percentile for height and between 10-25% for weight (nonadjusted). It's too early to tell if she will continue on that path, but she is a better eater than Charlie so I'm hopeful.
Is your LO tall/short, thin/chubby?
