DS has had awful reflux from about 2 months old, now luckily at 6.5 months we seem to be over the worst of it. My mum mentioned that she had read somewhere that reflux is more common in boys, and especially first born boys.
Just wondering if this theory could be true, and what the science behind it could be? (mum is prone to lots of 'I read somewhere' stories but forgets the details!)
Would be interested to know what you think.
