Quoting Aliyah'sMommyBri :" i gave LO her cup at lunch time at first, then lunch and breakfast... she just got used to it because ... [snip!] ... she was very easy going with the whole thing, and had been drinking out of one all together at about 10 months. try these... "
Try those! Or even the one that is taller with no handles...still like a bottle. I think they are blue with turtles on them. I bought six different sippys and those are the only ones LO would take. After a few weeks on those, he can take any of them!
Also, TOSS the bottles. All of them. Do not go back to the bottles, even if she suddenly doesnt like the sippy anymore.
