Well I think 1 yr is when you wanna rule out bottles, so I guess he’s making that easier on you! Haha but I understand where you’re coming from. You want him to have liquids, all you can do if offer! And off frequently, that’s all you can do. Like you said he’s peeing, not showing signs of dehydration? Every baby is different. But you said you’ve tried cups, maybe try a straw cup? My daughter loves that. But she’s about to be 19m comes November. Loves water! But for the life of me can’t get her to drink a full cup of cows milk a day (only sips here and there) let alone the 500ml theirs suppose to have/day. And she absolutely cringes at toddler formula, scrunches her face right up and pushes it away
Have you tried letting him do it independently or offering it at meal times
He will scream and cry and throw him self off my lap as soon as I sit down to feed him the bottle as well sometimes he won't even entertain the idea of drinking
