What made me so annoyed about this is the assumption that girls will be responsible for childcare.
That may reflect where we are now.
However if we are ever to get the general population to take children and childcare seriously, then it has to become something that boys and girls think they are both responsible for.
To start with teenage girls, telling them that they can't have it all, makes the grievous assumption that only women can take responsibility for looking after children.
I know, clearly (as I am not a stupid woman) that we women bear the children, but it does not mean that we have to take the responsiblity for staying at home and looking after them.
If you want to do that, then that is absolutely your right, and I am all in favour of women who choose to stay at home. I am also, though, in favour of those who choose to go back to work.
But more importantly, I think it is truly crucial for our nation in the future that men regard the welfare and day-to-day care of their children as their responsibility as well.
No longer should it just be the preserve of us women.
