Hi again,
I tried putting DD2 onto Size 4 teats and put the handles on her bottle. Now she is drinking all 3 bottles, although I decreased the amount of her midday one so she now has two 240ml and one 180ml bottles.
Have you tried putting the handles on the bottles? Its a bit of a novelty and works a treat. Bubs is too amused with drinking on their own to notice that they've actually drunk the whole bottle, he he.
Good luck [:)]
