Reversal booked!!

Hey all, so I'm 25 with no kids and my boyfriend is 28 with 3 kids from a previous relationship. He had a vasectomy at 24. We've been together for just over 3 years and have an appointment to have his vasectomy reversed in March. I'm just hoping it is successful 🙏 I can't wait to start trying! Any success stories? Also how long will he need to rest for to make sure things heal best as possible and any other helpful tips or anything to share? Thanks for reading!
