My son is 3 almost 4 in August, it was super easy to take him off the bottle but now it’s time to transition to a straw or regular cup he refuses, he would rather be thirsty and that scares me so I give in . I have started today to take away his old soppy cup during the day and only give him a straw cup or regular cup, and at night give him his regular cup. Is that a good idea? Also any tips on how to get him to actually try the straw ?
