Suddenly refusing bottle feeding 😞

Jeevi

My 12 weeks old LO suddenly refusing bottle feeding, since birth he’s been used to bottle and formula, I tried everything for him to drink through bottle but nothing seems to be working 😔😔😔 I’m so frustrated!!! Please let me know any way that I can make him drink formula? ATM I’m breast feeding him but I want him to drink formula as well so I can go back to work .
