Charl,
We switched to aspirin when the surgeon told us to ( I honestly don't remember how many weeks post surgery it was) - and yes, I was VERY nervous - but in the end, she did fine, and wow did we appreciate no more needles!!!
As for the water, I know they have you drinking alot immediately after the surgery, but check with the surgeon- they forgot to tell us when to stop pushing the water, and a few months after the surgery we asked about it and he said - oh, you could have stopped that as soon as you went home!
However, I will say this - we found that when we didn't push the water, her pressure and heart rate went up, so we find that our s need to drink at least 50 ounces of noncaffeinated fluids per day to keep their heart rate and BP at a good rate. I'm not sure that's usual, though, I think my s just tend to be very sensitive, as lots of other things (for instance, antihistimines) tend to have the same effect on them. I'm not sure if they determine the amount of fluids by age, weight, or individual circumstance, so my advice would be to check with the surgeon.
Dr. Scott is very good about answering his email - and remember, there are no silly questions when it comes to taking care of your children!
Also, think about the visiting nurse, it sounds to me like it would help you!!!
Glad to hear things are moving along for you and Molly!! You're doing great, Charl!! Keep up the good work, and remember, we're all here for you - ask all the questions you want - this is the perfect place for that!!
Take care!!
