lol arimeh ikwym but i think the formula warning is more for people who would dilute it to make the tin 'last longer', whereas the CHN said to me if bubs is waking up during the night (and often not drinking much of the bottle you give them) its cause of habit and 'weaning' them by diluting the formula til its just water (hence making bub realise theres no point waking up just for a bottle of water), but if you know your bub is waking for nutrition reasons e.g still young, not eating much in the way of solids etc, then keep giving them a nite bottle.... hope that makes sense!
