Thank You Gift to RE/infertility specialist/nurse

Hey ladies

I was just wondering if any of you have gave something to your RE when you got pregnant? I was struggling to conceive for three years and after going to infertility specialist I finally got pregnant through FET. I’ll be seeing them for last time next Friday and I was thinking to give them something or do something for them as a thank you. Any suggestions? What you have done for your doctor and nurse?
