My 8 month 21 day old baby will not eat formula. Flat out refuses it in bottle, sippy cup, everything. Tried flavoring it with banana rice cereal. Nope.

I’ve been ebf since he was born but I’m over it. He’s started biting me and then laughing. He thinks it’s hilarious. I do not. It’s to the point where he’s only feeding at night. The daytime feeds he eats for a few minutes and bites me. I need a full nights sleep! I can’t do this anymore but if he wont take formula or a bottle (last time I tried breast milk in a bottle he refused it). What am I to do? I feel like I’m failing him.
