Hey! Long time no see (we cant get facebook here cause of government restictrions) Been wondering how you and baby are.

We have been through a few different formulas for same reasons, settled on Heinz for DD. Ds1 used a HA formua and that was brilliant.
The main thing we have been told is dont just change formuals suddenly, but to do it over a day or 2 mixing the formuals together so the tummy can get use to the difference start off 70-30% then work round to 30-70%

Hope you have more luck soon hun
