I was told you should never have carbonated drinks bc it will stretch your stomach. As far as drinking alcohol my nutritionist said I could try wine at week 6 post op. At home of course to make sure your stomach agrees with it. I would say you probably won't be able to have beer again!
I'm a nanny also. My surgeon told me don't lift anything over 7lbs for a month. The kids I watch are 2 1/2 and 5. It's difficult sometime bc I forget. I'm almost 2 weeks out.
