First of, he eats and drinks -18-24oz of water so well during the day on top of his 8-10oz of milk. When we weaned his milk bottle at 14months I replaced it with water in the bottle. It was fine and okay before until lately, his first wake up at night is 10pm. He takes 10gulp of water the rest is 12am and 2am then he just have 2-3gulp. Then he will wake up that his diaper is overflowing because of so much water. Not sure what to do as we are still cosleeping and we just want a decent sleep that we never got since we gave birth. I guess I just expect a lot to get better soon. I get a lot of mixed advice. Some mothers says keep the water bottle at night because its good for toddlers to drink lots of water and good for them. Some mothers says weaned him from that water at night so he will not get used to it and make it a habit and also will be good once he potty trained. Last night, he cried and tried to kiss me to give him water for an hour and he woke up twice to asked for it and I said no water tonight. We can have it tomorrow morning. I need to know others perspective.
