Throw them out. He’ll get over it.
After one of my grandchildren bit the nipple of his bottle I said no more bottle you have to drink the milk from a sippy cup he would not drink it lol finally got thirsty n started to drink from the cup . Didn’t take long .
I cared for all my grandchildren since birth when their parents had to work or school .
Hide them dont give in Eventually he will be thirsty enough to drink out of them
Take them away. He wont let himself starve to death. Give him a cup with a straw
