Cups and high chairs

So, awhile back I had mentioned that big guy got a certificate from school about graduating from sippy cups. But, at home he was still using them. This week has been a turning point. Hubs has been forgetting the back-up-just in case sippy cup at school and he's been doing just fine. And awesomely enough he's been wanting to drink from a real cup! So every night at dinner. He and I share a little cup of chocolate milk, mmmm. With this new cup drinking, big guy has also started protesting immensely about the use of his booster seat. Not interested is clearly expressed in the screams and back arches and sobbing I get when I try to put him in. And we've been, well, not as successful at giving this up as the sippy cup, but we are working our way there!
