ds is 15 months. Doesn't talk. He says "da" and "der" a lot, and is a pretty effective communicator with pointing, tugging and the monosyllables he does have. I think he says "dox" for "socks" but that's absolutely it. Definitely not "mama" or "dada".
I know he understands what we're saying - he follows instructions, fetches things, joins in games when prompted etc - so I'm not worried about his hearing.
He does have a very articulate and loud older sister, which I know can slow things down. I'm not particularly worried at the moment, but a couple of people have expressed surprise he's not yet saying words. We fell out with the HV long ago, so I'm not going to ask her...MN is a far more reliable source of info as far as I'm concerned.
