we have been going thru this with MR H too... i swear it is a school thing because we went thru it when MrI started school too.. Not only are they being taught to be more independent they also have the bad influence of 19 other kids lol
I know that that doesnt really help but i found you just have to sweat it out and it will end eventually!!
only other thing i can sujest is pack her up and send her to nanny's house ROFL
