No no, they’ll happily tell you they’re literally using the kids as bait. You arrest the kid (who usually is a US citizen), the kid gets a phonecall with their parents, you arrest the immigrant parent(s) when they show up to say “what the fuck why did you drag my kid off”. Depending on how lazy the ICE agent is, you might deport the kid with the parent (the parent has to request this IIRC), or place them in foster care (with admittedly no way to reunite them). If the kid isn’t a US citizen, you don’t even need to deport them to the same country as their parents, put them on the same flight, or ANYTHING.

Don’t forget literally snatching children as “bait”. Kid’s a birthright citizen, but if you arrest THEM and they call Mom about “some people said they were from ICE and they took me away from school”, you can arrest the parents when they show up and deport THEM instead (and often put the kid in foster care instead of sending them with their parents to whatever country of origin.
