Bottle to cup

I just want to say, I love when people tell me to "put some juice in the cup so your son knows it's something yummy" girl my son don't give a fuck 😂 he doesn't like juice lmao he will only drink water and milk. If his bottle is not white or clear he don't want it 💀

Yes I've tried putting water and milk in a sippy cup, I've tried so many different cups from all types of nipples and even straws. Yes I've tried leaving it out all day and just letting him "take it eventually" all that caused was for him not to drink anything the entire day so I guess at this point idk what else to try. I can't dehydrate him for days, he loves drinking water.

He's almost 2
