Sounds like a crazy show! We have one in the us called 19 kids and counting. The family supports themselves, which is nice, but you can tell they have no plans on stopping having more, but they are a bit up there in age, and the last baby was born very early and very sickly.
My mom has a friend a lot like them. They wound up with 12 and had to stop because the last one came out so sick. Seriously, a woman's body can only take so much!
