Our DD's reflux was also mild and we were prescribed a reflux formula called Enfamil AR.
Yes she has started solids, although does not take much. She prefers her milk way more than solids. To be honest, once starting the prescription formula, she has not had any problems with her reflux. We did have to switch back to a normal formula when we came back from holiday, as we had run out of formula and had to wait for her prescription to come in, and it was a nightmare, so am very hesitant with weaning her from the formula.
