My now 15 month old had some feeding issues so we still haven't made the switch from bottles to sippy cups...and now all of a sudden he is OBSESSED with his bottles!

I'm wondering if anyone has used the sippy cup spouts that fit on the Avent bottles? We use Avent bottles and I'm thinking maybe that would be a good transition for him since he doesn't like straw or regular sippy cups yet! If you used them I'd love to know if it helped your transition or just made it harder to get rid of them!
