Is it okay to just cold Turkey stop giving him milk and only water he won’t drink juice either unless it’s from my cup he will drink anything from my cup but he will make a big mess if I only ever give him drink out of an open cup he won’t even drink hot cocoa (I poured some of mine into his sippy) he wouldn’t drink it out the sippy only my cup he will only drink milk out of his sippy and he still wakes up at night for milk I brush his teeth every morning and night but I want him to drink more water. Before he was 1 the drs told me i could give him pedialyte and apple juice for constipation and he drank it fine then but now he only wants milk. My question is will he dehydrate himself or will he eventually just drink the water ive tried to get him off milk during the day and did the juice in a cup slowly watering it down but he had nothing to do with it he’d take a sip then realize it’s not milk and throw it down then sit at my feet and yell at me until I caved.
