I've noticed Jaeden (my 4 yr. old daughter) is really good at learning new words and using them in different contexts.  For example, we were at the park a couple of days ago and Jaeden had met another girl the same age as her so they were running around the park.  Jaeden stopped and looked at the other girl and said, "Are you swift?"  The little girl looked at her not really sure how to answer so Jaeden asked her again with the same response.  Jaeden then explained, "Swift means fast so are you swift?  I'm very swift." and off she went running again.  It was so cute!

Yesterday Ethan and Jaeden were making some pictures using glitter glue but the tubes were almost empty so it was very hard to squeeze the remaining glue out.  Jaeden was explaining the meaning of 'stain' to Ethan but it wasn't really what it meant.  (I can't remember what her explanation was, though.)  Anyways, I proceeded to tell her that the word 'stain' means: something that's very hard to get out.  She then proceeded to tell Ethan, "Yeah, so this glue is called a stain."  as she's struggling with every ounce of muscle in her to get the rest of the glue out.  :)
