DD was duck at about 13/14 months I should think, but she really wasn't an early talker at all (I was quite worried at one point) and only now, at just turned 3, is she really speaking properly (now she won't shut up)
DS is 9 months and has been saying 'hello' for about 2 months . He can also say DD's name and 'mama' discriminately, and 'dada' more indiscriminately but pretty often to or about DH
i don't think he's as physical as DD though
