My daughter is now 15 months old. She NEVER held her bottle and I didn't think I would ever be able to get her to drink out of a sippy cup. You need to try the sippy cups with the soft spout, they are wonderful...it feels just like the nipple of a bottle so it's easier for them to adjust. They have different brands if you go somewhere like Target...they have a big selection. But I got my daughters first cup at CVS....believe it or not it was made by 'Pampers' and it was spill proof. She was only on it a few months and now she is on a regular sippy cup with the hard top! Good luck but I believe this will help!!! : )
