Although mine was breastfed, and may not exactly apply to you situation, we never do whole milk - instead we do yogurt which can be high-fat plus provide calories (if you worry about that) and is processed in a way that is different to cow milk (so transition is easier). There is also no reason to use cow's milk - my friend has a formula-fed baby that does not use cow milk at all. They use almond milk, which is also available to get. But with our boy, at resturants we always do water in a kids drink or apple juice. I agree with some other moms that there is no magical cut-off day for diets. Baby can stay on formula for the vacation or juice or whatever. Water might be right for kid. Also, you don't have to magically give them solids before one - you can still bottle or breastfeed after one. My DS is still BF (but we ARE phasing that out, I'm tired of it) There are so many options and you are going to get crazy rules from everybody. The only one to remember is not to give them honey until after one year.
