No - just give her the milk, seriously. Please don't give her water.
It's just a guideline, and she needs to put on weight and grow, which takes a lot of calories. Josh was taking way more than the box said to begin with as he was feeding every 3 hrs (and still does) so was having 7 feeds a day. He's now taking the minimum for his weight instead of above the maximum so it evens out. Every baby is different.
8.5lb is 3.85kg. So she could have between 580ml - 770ml per day. So that's between 19oz and 26oz as a GUIDELINE. An extra handful oz oz really isn't gonna make any difference.
My LO has never followed what it says on the tin and has always drank way over! As mentioned it is a guideline and every baby is different. Just feed your baby what they want and please don't give water.
We had a similar problem, my little one was taking up to 40oz a day. Spoke to Health Visitor who told us to keep feeding on demand & not switch to hungry baby. We are just shy of 6 weeks now and shes now taking 27oz. We're still feeding on demand but she just wants less. Baby will let you know
Sam is the same, he's never had whats on the box, at first i was worried i would over feed him but when he's had enough he just won't take anymore. He has approx 4/5oz (120ml) 6 times a day, sometimes he will drip drain the bottle other he will only take roughly 80 to 100ml of it.
Sweetie the other ladies are right - babies will only take as much as they need. Fran was on 4oz bottles at a week old and 5oz bottles at 3 weeks old.
Feed on demand and let her have as much as she wants - if she takes a little too much she will spit it up again.
The amounts on the box are simply a guideline, not a golden rule you have to stick to.
Please know that you are doing nothing wrong hun and the amount your LO is taking is just perfect xxx
Edit - oh and please don't give him water instead of milk - he really needs all the calories, vitamins and minerals. The only time you should give extra water is if he is constipated or it's an extremely hot day.
