Hi, she is on S26 Gold which she's been on since she was 3 days old. The only thing different that I can think of is that we've recently started her on solids, she was fine with the fruit purees/farex but in the last week or so she has started on the heinz pumpkin and potato. I think I'll take her to the GP this week just for a quick check up, she got her first tooth this week also so I wasn't sure if it could be related to that even. Thanks for the help.
