DS is just over a week old and is FF (currently on C&G first infant milk). We have been using TT bottles and there were no issues initially, but for the past 2 days he has been really fussy and unsettled after a feed.
He brings wind up fine, but then afterwards he's wriggling around in pain, almost like he has bellyache.
I don't know what to do. Could it be the bottles or perhaps the formula?
Please any tips from anybody would be a godsend 🙏🏻
