Hi,
I have a bottle with both measurements, so here goes!..
I estimate she has probably a bit less than 12oz (360mL) of water a day, and 10 1/2oz (300mL) of milk per day. Does that sound like a good amount?
I have been avoiding juice (even diluted) as she seems to love it, and I think she will work out that it's much better than water and only drink juice! She had a bit at hospital, which was a god-send as it was novel and 'yummy'!
Over the last few days I think she's evening out in terms of her fluids and food, and while her nappy in the morning is not as full as it used to be, she has wet nappies for the rest of the day. I think she's working to switching to more food and less milk.
