How can i gain weight in my breasts and butt?

Im 18 I've had a child and I've gained no weight in my breast or my butt and I want to know is there anyway to make them grow all my friends are thick and they dont even have kids I want to get like them, what can I do?

If by thicker you mean more all around weight, like in yer boobs, butt, stomach, hips thighs and all that mess, than eating more fatty foods should put weight on, unless you work out a lot those parts of the body should mainly consist of fat, and the fat that you'd gain from eating would go to those parts of the body and if distributed nicely it'd give you the body that you'd hope for although you may have to work out the abdomen to keep too much fat off it if your weight doesn't distribute too well..
