So DD2 is 7 weeks old, originally we started her on Aptamil stage 1. She showed signs of windy issues, crying episodes and discomfort when pooing. So we decided to change her to Hipp organic. She's been on this formula for nearly 3 days, and I know your meant to give her time to settle and she can pass gas and wind better and poos easier she is crying more after feeds and being sick. So I don't know what to do... continue or change back or a different brand? Any advice appreciated.
