dd2 is really hard work atm. 
One of the things that drive me mad is her constant greed for attention, to have the focus on her. I'm trying to get her to understand that sometimes she can't be, by for example completely focussing on dd1 and ignoring dd2 completely then. When I do this though dd2 talks non-stop, as she will always start talking to me the moment I start talking to dd1. 
Dh thinks she's too young - she's 2.9. What do you think?
