Breast Implants

I know it's always smart to wait to get breast implants until your done having kids but my question is--for those of you who had them before having children, did you notice a big difference in how they look after having your child/children? I have a 3 year old and not sure I'm done having kids but I'd love to get implants. I'm 5'7" and I barely fill an A cup. I'm totally uncomfortable with my body and don't wear certain clothes bc of how uncomfortable I am.
