Can any recommend resources (books, videos, etc) or other ways to start doing a bit of signing with a 17mo when doing a class isn't really an option because I'm back at work a long time now and also have older DC?
Not-really-relevant context, DS2 is obviously so hugely enamoured of being able to say "yes" and shake his head "no" to us now and it makes him so happy to be able to communicate that bit better, so I'd love to introduce a few signs.
