Oh, how very droll @izimbra
No, that's not what posters are saying.
They are saying that it's incredibly hard for anyone to have a baby and juggle it with work, especially if they are young and don't have a stable income.
Of course people without salaried and professional jobs have kids.
But the very worst combination is to be young, with no secure income (both the woman and the man), no means of supporting yourselves very well, let a lone a child.
This couple wouldn't even be able to get onto the rental market themselves.
No savings, no stable income, only been in their zero hours and self-employed jobs for weeks (because of redundancy.)
If they want to live with their parents and the grandparents bring up the baby, fair enough.
They don't have many other options other than benefits and finding a flat or waiting for council accommodation.
Yes, let them go ahead. BUT the daughter needs to understand exactly how hard it's going to be.
Then she can make her decision.
