NIckers- Hmm doesn't sound like they're explaining things very well to you.
As far as I know, just because he has risk factors doesn't mean there will be anything wrong. Kyla was at high risk because of her prematurity, she had her first test at due date where they said one ear she wasn't hearing low freq sounds, so she had the next test at 3 months (i think), this was ok but she still has to have one at 10 months.
