Thanks Lolly,
yeah, a bottle before bath time might be a good idea, or maybe after they wake up from their last nap. How spaced out should these feeds be? They usually wake up about 4.30 - 5pm after their nap, bath at 6pm and have their bedtime bottle at 6.45pm.
I intend to discuss this with my HV, shes very nice but a little bit useless :-/
