I feel like I can't really call them babies anymore. I still do sometimes, but just out of habit. Like when Dave calls their sippy and straw cups "bottles". I sure don't miss bottles. Speaking of cups, we're starting to work on open cups in the bath tub (with fresh water, not bath water!) and only using straw cups. They don't seem to like sippy cups much these days which means less cup changing for me, so I'm good with it.
