Sources tell two-year-old Landon and 10-month-old Logan were taken away from Major's apartment in Boca Raton on Wednesday (28Oct15) after obtaining a video featuring an altercation between their parents.

Michael's mother flew in from Long Island and the kids were released to her guardianship at her son's home.

The insiders tell Michael and Kate can both see the kids, but only if their grandma is present.

A hearing is scheduled for Tuesday (03Nov15), when a plan for the children's care will be put in place.

Michael told TMZ on Monday (02Nov15) that the DCF officials took the kids because Major arrived solo at his home to collect them even though she is not allowed to be near their children without a monitor.
