I don’t think she left the baby behind, they sent her home with an ankle bracelet and returned the child to her, probably until her case was finalized. Then the baby would have left with her and the rest of the family. They mention 3 kids, 2 of whom are citizens. Since she’d been here 5 years, it’s logical to assume the baby is one of the 2 kids born here.
The article is about child services taking a nursing baby away when the mother was arrested. I agree that is not good for the baby...but if the mother wasn’t illegal, she wouldn’t have that problem, then, would she?
Maybe she didn’t leave the baby behind. I don’t know but your count looks right. However, it wouldn’t surprise me to see her leave the child behind. Recall the Mexican who took refuge in the church left her child behind.
