Then, I bought a Born Free Training Cup. I had avoided them in my first round of cup shopping because they are a little pricey. TOTALLY worth the price (best price I have seen is Diapers.com). The spout is pretty similar in shape & texture to a bottle nipple. You can also take the handles off so it looks like a bottle too. For the first few times I held it & fed Maggie before she went to sleep at nap time. She drank out of it & before long it was all she used. We still gave her a bottle at night for a while. Then by 1 she started drinking out of any cup I gave her.
I thought maybe it was just Maggie, but seems like the same thing with Alex. She will not take a sippy cup unless it's the Born Free Training Cup! Now, she is 10 months & pretty much done with bottles thanks to these great cups!
