Man I don't know how you do it with kids. You are being the rock for your kids In a time or turmoil. It seems much like others in the situation that the kids end up with a better understanding or the situation and more maturity than the WW. To me it seems she's lashing out and not knowing how to deal with her situation. Emotions leading behaviour. Tbh I somehow think that hormonal changes have a lot to do with this behaviour and they just don't know how to manage or deal with it. Keep being the rock for your daughters and show them the demeanor they will appreciate, not that it feels like you guys are teaming up on ww, you are showing her stability and balance when she is in a state of perpetual turmoil.
