I am 4'10 1/2" too. My shoe size WAS a womens size 4 (compatible to a childs size 2), however after having my DD my feet grew and now I wear a womens size 5 (compatible to a childs size 3).
My DH is 5'9" so he is really not that much taller than me - at least I don't think so, but when we take a picture he seems to tower over me.
MY DD is only 2 1/2 but the doctor has already told me that she is going to be a peanut (she is only in the 5%).
I am glad I am not the only one under 5'!!
