My dd is 12 weeks old and formula fed. She has suffered with reflux since birth but the last week has been truly awful. She was prescribed infant gaviscon at 6 weeks but that didn't stop the reflux, it just made her constipated. We've tried management of it but had to move her onto anti-reflux milk this week. She had two good days of it, though she now has hideous constipation. However, the last two days she has vomited with the anti-reflux milk too. At a loss as to what to do!
