Success! After school the other day we were in the kitchen. My son (15 months) asked for “more” to eat by signing. His sister was paying attention and got him a snack. He responded with a big “Daku!” Sounds like thank you to me. 😊 I love that he is learning by watching and listening to us. I wasn’t sure if it was a one time thing, but it isn’t! He made the connection and when we do something to help him he more often than not says “Daku” with a big smile.
