DS used to be such a great sleeper bar occasional phases easily identifiable as teeth / cold etc. Lately he has been regularly wakening the small hours and seeming just to want to be with us and "chat" (for which read randomly babble with the occasional word). His vocab is increasing all the time. CM theory is that he is just wanting to practise and chat. Any ideas on if this a known "thing" and if so, what we can do about it? DC2 due soon and would like to get my sleeping angel back!
