K.S.
I'm just peeking here to see some of the ideas. I am in the same boat, and have been for months. My son is now 7 months old, I've gone through every different style bottle/nipple I can find, and still, he refuses. He won't take a sippy cup yet either. I try pretty much every day with a bottle of expressed milk or juice.
I think I'm just bound to bf'ing until he weans himself! (not really complaining too much because I do love the bond!)
