To Sippy Cup or Not To Sippy Cup

Hayli just HATES sippy cups. Conrad and I were trying to do the transition before the doctor told us that we had to remove Hayli from the bottles and move to sippy cups only. The only time that we are 'allowed' to give her a bottle is at night-night time. This conversation with the doctor happened on her one-year check (a while ago anyway). Of course, we still have been using the bottle since Hayli has not found a single sippy cup she likes. I have spent at least $200 on different sippy cups, and trying to trick Hayli into using them. I even brought only a sippy cup - no bottle - during one of our group walks, and instead of this plan working it completely backfired. Hayli screamed all the way home because she wanted the milk but NOT from a sippy cup. (That was a long drive home!) While looking for the ketchup today, Conrad suggested we try just one more type of cup... and of course... father knows best. Hayli seems to think that this cup may be okay...
