Feedback needed!

Lauren went to the ENT today and we found out her tonsils are HUGE and very unhealthy. She is having surgery March 31st. I have been a mother for almost 14 years now and I have never been through this and I am worried. I need to hear from some readers (if I have any left) about staying calm when your baby goes in for surgery. I am worried of course about her being put under BUT I fear more about how she will recover. She doesn't do well being sick. And I mean it will take her DAYS to eat if she throws up. She has been close to being put in the hospital with just a little bug. We go back next Wed. the 23rd to talk about everything so I need feedback from you!! Thanks!
