How long can my baby boy be nil by mouth?

Your question to how long he can nil by mouth; a question you need to ask the Drs, but he'll hav a drip with essential liquid etc.. As for the comment on him having a bottle; it's NOBODY else's business when you should stop him having a bottle, every baby/child is different. People are in such a hurry to make their little ones grow up. Anyway, if he is on a bottle still, please pay no attention to the comment that you should stop, as long as he's happy and you're happy, there's no issue. Good luck with the op, it is scary, but he'll be well looked after.
