Hi Kathryn,
Happy New Year to you too
Wow, I cannot believe that Sophie is going to be 1 soon, unbelievable how quickly time flies. Hope she has a good day
With regards of when to drop to 1 bottle, I would completely follow your lo. If she is still taking both her bottles so well, I would leave her on it until she is ready to drop it.
We seem to be going through this phase at the moment. Thomas has started fussing over his morning bottle over the past few weeks where he will only take a few sips of it and then pushes it away. He would rather have his breakfast. He is 18 months in 2 weeks time, and I am thinking about dropping the morning bottle as he just does not want it.
I too have tried to get him on a sippy with his milk in, and have just failed constantly. He looks at me as if I am mad when I put milk in instead of water / juice. I am just going to keep on offering a few oz in a sippy every morning with his cereal in hopes that he will start taking more out of it. He too eats a lot of yogurts during the day.
With regards to the transition to cows milk, I started a sticky poll just before Thomas turned 1, where I asked about transitioning to cows milk. In the end we just went cold turkey and Thomas did not notice the difference at all. He actually started to take a lot more than the formula he used to drink. Just to warn you, it can effect their bowel movements, but that is also discussed in that link.
