Most meds are safe while nursing, bring it up with your team. They should know your situation beforehand bc they can choose safer medications to give you. This could allow you to not have to dump at all. Example: for nausea zofran is better than phenergan if you are nursing.
Definately bring your pump. Hospitals have them, but not outside of OB. They could track one down for you, but if the nurses are busy it could take a long time.
Some surgical groups want you to be done nursing b4 surgery bc your body will be in starvation mode. That being said, baby is eating other food too and not relying on you for total nutrition so it might be ok.
I totally get baby led weaning, it is what I did. One decided to be done at 15 months, the other at 18 months. I started the surgical process as soon as I was done nursing.
Even if they make you wait it shouldn't be too long. Unless you plan on nursing until preschool, but that would be another issue for another forum. Lol 😄
