Over the last couple of weeks, I've been sitting the kid on the edge of the sink and explaining how I'm making a bottle for her. I show her the steps, do it all right in front of her.
Most of the time, she finds it fascinating, ahe realizes food is coming and she doesn't freak out. A couple of times, when she was starting a hunger-induced meltdown, making the bottle in front of her actually calmed her down.
And I'm pretty sure that, in just a few more weeks, she'll learn how to do it herself, which should free up a lot of time. As the saying goes, give a kid a bottle and she eats for a few hours; teach her to make a bottle, and...and you'll probably end up with a giant can of formula spilled on the floor someday.
Let me get back to you on that one...
