hiya, i have a little girl who is 3 and a half, she has always been smaller than average height and weight since she was born. She was quite ill over the christmas and has had on and off colds since. she weighed just over 2 and a half stone before christmas. Over this time i could feel her loseing weight. Family and friends also commented on how light she has got without me saying anything. she got weighed again on last monday and she weighed just under 2 and a half stone. i weighed her again on wednesday and she'd lost 3lbs and then weighed her again this morning and shes lost another 3lbs. The doctor doesnt seem that concerned over it but im worried sick, can someone please help, abit of advice or something please.
