Having Rhinoplasty After Pregnancy?

You can have it as soon as 3 months after delivery. You cannot breast feed for at least a week after surgery as you will be on antibiotics and other pain medicine. You will have to either supplement or pump a lot of milk and store it in advance.

It is acceptable to have rhinoplasty a few months after you have given birth to your baby. However, you must be emotionally AND physically ready for an elective procedure. Breastfeeding can be done in the postoperative phase; however, narcotics do pass through breast milk for the first few days. To prepare, pumping and storing breast milk for this time period is advisable. I strongly encourage you to communicate with your OB/GYN about when would be best for you (and your baby) to pursue rhinoplasty.

Sarah,
This MUST be your first child. You are going to have your hands full with the baby and the last thing you will need is the stress of any cosmetic operation.
From a medical point of view, most doctors would recommend that you do NOT take certain medications which may enter your breast milk and be thereby administered to the baby. The list of such medications is very long.
Since breast feeding is extremely important to your baby's well being an development as well as your bonding with him/her, to be safe you will need to postpone taking such medications (and operations which will require you take such medications) until you are done breast feeding.
I hope this was helpful.
