Hi, all, I have a mom with a 10 month old, who has been dx with hyperthyroidism. Her test is scheduled for Friday. She will be taking I-131 (a sodium iodine capsule), and TC-99 (IV injection). She knows she will have to pump & dump. What we're wondering is for how long.... Mom really is not ready to wean. Thanks for all of your help and support. I LOVE this group!!!
