I can't remember . I think that's why you have to get there fast before they work themselves up. I would pick her up until she calmed down and then start shush/pat thing again...although I think BW was very keen on consoling in the cot....
However have just read some of your earlier posts about daytime naps, and I think she sounds as if she is not gtting enough daytime kip, and poss getting overtired.
I,m sure the guidline at this age is 2 hours am, 3 hours pm, and possible catnap at about 5.30 pm for abouy 40 mins to get through to bed time. It sounds as if your lo is doing the catnap thing, but needs to be helped to go to bed at nighttime sleep.
God, it is so hard isn't it? I remember that despeeration at a none sleeping lo when every one elses would sleep anywhere. My dd slept at night at this age, so hv not helpful at all, despite the fact dd was so tired in day and cried non stop.
ds who is older would sleep anywhere, so nothing prepared me for that . It does get better, dd 23 mo now, and sleeps all night.
