My 15 month old baby won't drink enough

[MummaBear2019]

I've been having this issue since he was introduced to water around 7 or 8 months, he just isn't interested in drinking it. I didn't feel that worried when he was younger because he would drink enough formula, but now he's just on cows milk, water/juice, I know he isn't drinking enough! A typical day would consist of 8oz of milk in the morning, 2-5oz of juice/water throughout the day (5oz being a really good day) then 3-4oz of milk before bed. I've spoken to the HV and doctor, HV said just to keep trying, doctor said to try him on sugar free coke, lemonade and tea (mm no thanks). Ive tries various bottles, he seems to drink more out of a free flowing cup. I'm just so worried he's going to dehydrate especially in this hot weather.

Anyone else had this problem or has any advice?

I gave my DD bashed up ice cubes in a cup when she was little. Straight down in warm weather! Cup of water? No way! 😁

My mum was obsessed with getting ds1 to drink as he just didn't apart from his milk... he survived and is 16 now.

Ds2 though l was a bit concerned over. Ds1 loved his milk but ds2 loved his food more and dropped his milk. Spoke to my HV and she said as long as he has approx 12oz of milk then not to worry.... which is what he had. As ds2 got older he did drink more fluids and now drinks more then ds1.
