OH Deb I am so happy for you! We are in the same situation here and I can really truly understand how excited you are. DS accidentally had butter one day shortly after we arrived in Germany and he seemed fine for 24 hours, so we started him on bits of cheese and some tastes of yogurt and he is doing well! I did try straight milk one day and hew as a total nightmare, but he was cutting 4 teeth at the same time, so I couldn't be definite about it. I've not offered milk again but have given him a few licks of my ice cream now and again and cooked with milk in it (pancakes, etc) and no problems yet! We have actually stopped label reading and stopped thinking about what we give him - if he wants to try something on my plate I don't say "noooo, there is milk in that" - and we are doing well.
It is a HUGE load off of your mind, isn't it? Just feels like life is so much simpler now. Sooooo very happy for you and your LO!
