Heeeeeeeelp. What worked for you when transitioning your LO off of bottles. We just had an epic meltdown trying to give my one year old milk in a sippy. He will take water from a straw cup during meals, but won't take milk from any sippy we have tried.
I kind of want to go cold turkey on him and just have a battle of wills, but I'm too much of a wuss and worry about him dehydrating.
This is worse than changing him from the co-sleeper to the crib in terms of resistance. I'm so sad for him, he is really upset!
