2-3 weeks to heal is wishful thinking. That's the first healing stage, after which my surgeon allowed me to do things more than light lifting. 4-6 weeks to return to work. 3 months to have sex. But healing generally continues until about a year post op. Incidentally it took me about a year to be able to orgasm (it's been several years now and I'd say it's probably easier now than pre op)

My surgeon was a reputable surgeon at a reputable institution and showed me pictures of her work during consultation and gave me realistic expectations. There were complications (there often are) but they were ultimately temporary issues. And the trans community gave me a realistic but positive expectation compared to my personal experience.

If you have any questions I may be able to answer some. If anything push your daughter to look up and ask around about surgeons (word gets around about bad ones) and push her towards reputable ones who are willing to make her feel comfortable in their care and who explain what's going on and what's going to happen to her.
