Rejects Formula/Bottles

Hi Mums, my 11 week old is currently EBF and I’ve been trying to get him to take 1 bottle before the night sleep or 1 odd bottle when we are out for a few hrs during the day- which he upright rejects. He used to take bottles fine till he was 5weeks old after which he started to EBF. We have tried different formula brands, bottle teats, dad feeding the bottle, different temp, but nothing seems to work. He gets really upset, screams and wont drink any. Not looking for pumping, just would love to know if you have been successful to introduce formula/bottles to your baby.
