Baby drinks loads of water

[Nannyx2]

Can anybody advise me my grandson is 15months old stopped drinking milk a few months ago his choice and we put water in a bottle and that was the start of it

He drinks a full bottle of water the way a hungry baby would drink milk

He is a good little eater and we always ensure he has lots of fruit veg fish etc which he loves he has porridge for breakfast
Lots of little snacks
Pasta meals freshly made for lunch and what we have for tea

He has started waking up through the night drinks a full 8oz of water every few hours

We are changing his nappy’s by the hour
When I say we I have him 3 days and 3 nights a week to help out

I keep telling his mum to take him the doctors it’s my sons baby .

His mum seems to think that the doctor won’t be able to help and he will grow out of it

Any advise or anybody who had experienced similar would be helpful
Thank you in advance

I would have a read of this

Babies that age would ideally be drinking milk daily - either formula or full fat cows milk. Have you tried milk when he wakes.at night? He could be waking because he is hungry and needs milk.

Excessive thirst can be a sign of diabetes. It’s probably not but definitely worth going to the GP to be on the safe side.

I too would get a check up at the gp.

Sounds like it could be habitual however best to get checked. In the mean tone swap bottle for a zippy cup or rimmed cup and don't offer a full 8oz in the night

I keep telling his mum to take him the doctors it’s my sons baby .

Why don't you tell your son?

On the other hand you appear to have nearly 50% custody of this baby, why not ask permission and take baby to the DD's yourself?

I'd be very concerned about the possibility of type 1 diabetes, given the excessive thirst coupled with increased urine output.

Tell your son he needs to go to the doctor's. If it is diabetes it's very dangerous to leave it untreated.

While of course excessive thirst can sometimes be a sign of diabetes- there is also a direct link between drinking more and peeing more.

Is there is a reason he has water in a bottle rather that a sippy cup/beaker? It could just be comfort thing - using the bottle teat like a dummy.

So if he has milk in the bottle instead… does he just not drink it?

If it were up to me I’d give at least one bottle of milk eg bedtime and then give water in a silly cup and see what happens. Then you could see if it’s genuine thirst or comfort sucking.

Yes, but drinking more without peeing excessively likely means you need to drink more. If you're drinking more because your body needs more (say due to heat or exercise), you don't see the fluid output increase that much. If he's compelled to drink excessively and that is resulting in peeing excessively that suggests that his body doesn't actually need the fluid.

Pointing to something untoward- it's a classic sign of diabetes.

I'd just to make sure he was getting enough dairy and calcium else where. Yoghurt, milk on cereal and porridge, cheese. At least he's hydrated though!
