Sudden bottle refusal help!!

My son is 3 and a half months old and is exclusively breastfed, we introduced a bottle of expressed milk at a few weeks old and have given them as and when needed. He last took a bottle 3 days ago fine but last night and today has just been crying when we’ve tried. Any help or advice is greatly appreciated❤️ I was out for 3 hours and usually he’d have at least 1 feed in that time but when my partner tried he just screamed and cried
