@SerenePeach It may be perfectly possible to have children and work, but it's hard because, regardless of the "help" that others may give, the greatest burden for balancing everything still falls on mothers. Being a working mother, especially full-time, too often means doing it all, not having it all.
Increasingly women are deciding they don't want that. And guess what, they're not dropping the work part, they're dropping the children part.
If society doesn't make having children a more attractive prospect for women, then there will be less and less with all the unattractive demographic consequences that brings.
I am the only one of my siblings to have children. I'm also in a minority in my friendship group - of my close friends at university, only 2 have children. The rest, a measly £25 a week certainly isn't going to convince them. They spend much more than that on eating out and on the dog walker. All they see when they look at working mothers with children is an endless round of stress, compromise, unfair division of labour, sky-high childcare costs and very little free time or money.
My own view is that, if we want to boost birth rates, we're better focusing on families with two kids and persuading them to have a third and removing the child benefit cap makes sense in this regard.
