If it helps any - there's about 6 weeks between your DD and my DD2 - and she is on 200mls a feed every 3.5 hours during the day (she sleeps overnight).

On the formula tin it does say 5 feeds a day - and thats what she has? My DS was drinking around 240mls at this time though (fed every 4 hours and once overnight), and DD1 was probably around 80ml a time if that (she fed every 2 hours in day time and once overnight).

So it really depends on how often she is drinking I suppose?
