Uh honey - do you mean that you are diluting the formula? Cos it says on the tin that you aren't supposed to differ from the formula and water ratio - it can make bubs sick. I'd say make up less formula and then if still thirsty, give a sippy cup of water instead - but I would never give less scoops to water, simply because what it says on the tin

I don't see how it could. DD is getting 630mls of formula a day and 3 nutritious meals plus snacks of fruit/crackers. It's definately not the fact she's hugry because her tummy is still VERY FULL from dinner when she's demanding the bottle. The bottle in the middle of a night is really just comfort and only started just after we moved.

In reality it is only like giving her a 90 ml bottle followed by 60 mls water I feel anyway and she genearlly will have 90-100 mls water in one sitting anyway.

Apologies for the frank tone. Not meaning to shoot down your theory by sounding harsh just trying to write while DP's attempt at cooking is asking me to show him how stuff's done
