Sam, is there a reason for diluting the milk? I suppose that is what I am not sure about - is the intention to wean them onto water overnight or is it in order to increase their solids intake at night and in the morning?

AE - That is what I am hoping. A lot of littlies his age that I know have been sleeping through for ages and I was just wondering how long it can go on for!

Appletree - good suggestion - I may give that a try!
