"I want milk"
When my son suddenly said these words, we were so surprised that we didn't react for a few moments and he said it again and we were off celebrating. To some parents this may seem like something normal but for us, to get him to say anything is an achievement and for him to say the three words meaningfully, is a miracle.
Now we are trying to get him to say ! want .. with other words like light, out, water, etc.
Wish us luck.
