Gillian: Congratulations on a little walker! And keep with the signing - it's very impressive how fast it goes when it finally "clicks". Katmai did nothing in return for a long time, then just a few, and now suddenly can sign at least a dozen words. Make sure to try and teach interesting signs too. Katmai will do "more" and "all done", but almost all of his signs are things he thinks are interesting (rather than things I think are useful) like animals and toys. He still hardly ever uses "milk". I think he doesn't want to talk to ask me for things, he wants to talk to tell me things, if that makes any sense.
Sounds like our LOs are on the same page. Aubrey doesn't say much--just mama, clearly, and baba (dada) and boo not so clearly. But she's had a signing explosion in the last week. Yesterday she sat in her high chair and signed "more" and "eat" in succession. I nearly peed my pants and squealed I was so excited. So now we have ASL: "more," "eat/food," "milk" (boobies), and "up", plus our own made-up signs for ceiling fan and all done. Progress, right?!
