Hello! My son is 15 and has asd and anxiety He wouldn't drink milk out of anything other than a babies bottle But when he was about 8 he bit the teat and I didn't replace it because my ex said don't as he's to old He had a dietitian appointment on Friday and they said it's great that he started eating yogurts but he could do with my calcium especially because he doesn't brush his teeth So I was thinking of getting him a bottle and letting him drink milk out of it especially now because he eats cheerios Is this a bad idea?
