Hi,all my life iv'e been a slim girl but recently i think iv'e lost to much weight.Im 24,169cm high and only49kg.Iv'e got a 1year old son who is on the go all the time and i need a lot of energy to keep up with him:)i cant stand listening to people comments about the way i look.I feel ever since i gave birth to my son im just to slim and i can't put on any weight.I even went to see a doctor about it but she said that is becouse my family is slim i am too and i wont change it.I would love to put on about 5kg,how can i do it?
