How much does your 12-18 month old drink per day?

[UserThenLotsOfNumbers]

We are struggling to get DD 14 months to drink from cups (open and/or sippy cups), and so she still has 4 bottles of milk a day. Im worried her fluid intake isn't enough, as shes been suffering from constipation lately. She was prem, 5 weeks, and has been a bit behind with weaning, but overall loves food.

I wonder how her liquid intake (water and milk) compares to children of a similar age?

200ml formula milk first thing
120ml whole milk mid morning
Same mid afternoon
200ml formula before bed

I heard 1 litre is the recommended amount - oops.
If we're lucky, she'll drink a few sips of water with her meals. It depends how she feels really, sometimes she'll drink quite a bit, other times she'll totally refuse water. I've taken to watering down her milk a bit to up her water intake. Also giving her formula still as just giving her cows milk makes the constipation worse.

Food wise, she has a large bowl of porridge plus multivitamin for breakfast, two course meals for lunch and dinner, and snacks depending on her nap times.

Feeling a bit of a rubbish parent that's she's not drinking from cups yet tbh.

Any advice or suggestions welcome thanks!

*1 litre of fluid per day, milk and water, I should have said.

Doesn't sound far from what my 12 mo twins have. It hadn't occurred to me to worry... I thought as long as they had at least 20oz milk and regularly offered water it was fine x

Thanks
I found out today that babies should be giving up the bottle for cups at a year, so just feel behind. I let her have the bottles as if not, she wouldn't drink nearly enough.

Sounds similar to my 15 month old. Two breastfeeds a day then probably about 200ml water through the day.

At 12 months, mine was still having 2 bottles of milk a day (about 250 ml of milk). She started to talk it from a straw cup only around 13 months, though the 2nd one at bedtime was still in a bottle until 15 months. So about 500 ml of milk either in cup/bottle and a few sips of water until 14 months. At 14 months, she dropped the morning milk, so just 250 ml of milk at bedtime and a few sips of water. So between 250-500ml of milk and only tiny bits of water.

1 L sounds like an awful lot of fluid! The recommendation for toddlers is about 500ml of milk to age 5 or the equivalent in other dairy products and I doubt most children drink a further 500ml of water a day. Mine might drink about 250ml at a stretch!

Thanks for your replies, feeling reassured now.
