My little boy has had some trouble feeding (reflux, painful gas etc) so have been trying different brands and types of formula. Recently we've been making a mix of normal SMA formula and C&G antireflux in the same bottle and it's been working well. e.g. 3 scoops of normal and 2 scoops of antireflux. However when I mentioned this to the health visitor today she was horrified and said I shouldn't mix. The scoops and amounts are the same on the instructions for both types. So can anyone tell me why I shouldn't do this?
