DD2 wakes a few times a night but there is no routine to it at all, some nights it's 11.30 and 1.30, sometimes she sleeps until 2 and then wakes and wakes again at 5. Does anyone else's baby do this? I find it a bit wearing as although she's waking less its so unpredictable when she'll wake. Now she often chats for some time in the night too, so it takes longer to settle her.
