I have honestly lost my mind..
He's been to doctors 3 times as he has had diarrhea for the past 10 days!! It isn't getting better it's getting worse, they don't seem to be worried and told me just to keep a diary and if it still happens to take him back! I mean how bad does it have to get, I showed them this and she said 'carry on doing that' and that's it!!!  Any advice please 😩😩
