Congratulations on your decision to breastfeed and to desire to continue. In doing this you are giving your baby a gift of love nothing else can duplicate. The health benefits of breastfeeding are tremendous. The recommendation is breastmilk for at least the first year of life so you are doing great!
As for liposuction - this would mostly depend on what they use for anesthetic. Local and regional anesthesia are fine so if that is used, should be no problem.
Pain relievers such as those they offer in the hospital after delivery are also considered safe in breastfeeding so if you need
pain relief after the procedure, this should not interfere. You should be able to find out what they use and if they give you a sedative, check with a resource such as otispregnancy.org (you may have a local teratology hotline service available in your area also)about specific medications that might be used to sedate you. They are very current on these issues - more so than the doctors as a rule. It is not uncommon for the doctor to advise you to discard your milk to be on the safe side but in many cases the medication has not been found to be harmful so it could be unnecessary. By checking with this service you can get reliable information. La Leche League International can also advise you on this. (llli.org)
There is no reason at all that I can see to discontinue breastfeeding in this case. If it was not advised, you would be wise to wait until you were finished breastfeeding rather than wean early. The benefits are so worth it and your baby will be grown way too fast as it is - even though right now it seems like a long time.
Good luck.
