Thank you for the question. I understand that having a child is no small matter! Going through months of pregnancy and then delivery followed by sleepless nights and breast feeding takes a toll of any woman's body. I bet you can't wait to get back into self care and facial rejuvenation. There has been no conclusive study to evaluate the impact of hyaluronic acid injection to infant during breast feeding. As professional injectors we do not advise pregnant or breast feeding mothers undergo cosmetic injectables. When comparing the benefit of plumping lips vrs potential harm on a new born child, one might deduct waiting to be done with breast feeding before lip injections is the right choice to make.
