Unfit mom rant

I have a cousin who is younger than me by a few weeks. She has given birth to four children already and she's pregnant again. Now, I normally wouldn't have an issue, but she doesn't even have custody of her four kids and she's not even 6 months out of court-ordered rehab. I'm sorry, but what are some women thinking? I've lost three babies. Meanwhile, other women are having children they don't even deserve.
