Ugh! Nothing is worse than two needy kids when you're sick and a little needy yourself! I'm willing to be that it's a combination of her having been sick and then new addition the family. I found my DS1 got a little bent out of shape about 3 weeks after DS2 came home and it lasted for about 2 weeks, maybe it's just happening later for your DD? What DH did was he went to him once and held him, told him Mommy and Daddy loved him and he was safe and could go to sleep. The next time he went in he said the same thing but then told DS he would sit in the chair for 2 minutes and then he was going to leave and go to sleep in our room. DS accepted that and it went off without a hitch. Having said that, DS1 is the most easy going kid you'll meet and he was also still in a crib at that time. I hope that helps somewhat!
