hi ladies,
thanks for all the great responses.
I'm feeling much better now - no sleep and a what turned out to be a houseful of sickness and mummy with PMT as well was not a good combo. And also, realising that I don't have a great support network IRL, so thanks again ladies, I really appreciated it.
DD1 still disrupting DD2 sleep, but I have learned to distract her with her favorite DVD whatever works!
