In the past few months, I have noticed that, my DD1 who has recently turned 10 appears to be getting extra emotional just before MY period. Ok, I'm a grown woman so I do know when about my period is due, but it's like a back up early warning system. We'll be having a normalish day and then she'll start getting really upset about minor stuff, unable to stop herself crying, typical hormonal stuff. Then like clockwork MY period comes the next day. (DD1 hasn't started menstruating yet!) I'm not concerned but the few (female) close friends or relatives that i've mentioned this to have all looked at me like I'm a bit mad. I was really wondering has anyone else noticed their DD apparently syncing up with their own cycles before they even start menstruating or is it something I'm imagining as part of my own PMT?
