And we tell her that she has Down Syndrome. We don't make a big deal of it, we just bring it up once in a while. We own videos that have kids with DS in them, so it's easy to point out. "Lila, see that cute little girl with Barney? She has Down Syndrome like you do!"
Lila also has a lot of friends with Down Syndrome and sometimes I'll include the fact that they have Down Syndrome in conversation. "Lila, we're going to play with Roxy, Josie and Baby Lena today. Roxy has Down Syndrome like you do!"
Having Down Syndrome is a part of her life. We want her to hear those words from her family first. Words said with love. I am pretty sure that at some point in Lila's life she will hear those words from someone and she won't be feeling any love from them.
In the last few days I have read 3 different stories of people who were basically freaking out because their kid was "catching on" that they have Down Syndrome. These kids range from 7-12 years old. I have to wonder if these kids "caught on" to the fact that they have Down Syndrome a while ago but are just now letting their parents in on it.
