A.C.
There is a nasty cold that has been going around. It lasted over 3 weeks for both me and my 3 year old. We never took any antibiotics and it very slowly went away.
I guess the only thing that has me a little concerned is that your baby doesn't have a fever or ear infections and "seems to be fine", so the antibiotic is a little puzzling.
You could hold onto the presciption and try and wait another week to see if it clears up on its own, but maybe check with the dr. and make sure he didn't prescribe for a reason that you are unaware of. And if it's not better in another week you could always use the prescription.
I'm with you, I don't like using that stuff unless it's totally necessary. So, just double check.
I also used a vaporizer and some liquid Vicks at night. That helped with the congestion.
I hope he feels better soon.
