I bought a bunch of signing DVDs for my son at 4 mos old. I wasn't sure what he would sit though or even how much good it was doing him so early. We watched Signing Time mostly because mommy liked it :o), but he loved it even at that early age. As he grew older he did not give the same attention to the others, not even for 5 minutes. Now he is 14 mos old. He still watches them and LOVES Rachel (he has fallen for her). He has been signing milk, more, and dog since he was 9mos old. He is more prominant with his signing and is able to pick up new ones from me (like please and sorry). He doesn't talk yet and this was a GREAT way to stop the frustration screaming.Thanks Signing Time!
