The older kids are up for it, but the younger ones find it really weird,' the source adds. 'Brad just wants to see his kids and vice versa.'
Ange and Brad share six children - Maddox, 16, Pax, 14, Zahara, 13, Shiloh, 21 and twins Knox and Vivienne, 9.
According to court documents, the Superior Court of Los Angeles County determined that 'not having a relationship with their father would be harmful.'
The court determined that the children 'are safe with their father' and that it is 'critical that each of them have a healthy and strong relationship' with both of their parents.
However, Maddox is essentially free to go with either parent because of his age.
Neither Angelina or Brad have responded to OK!'s report.
