Wait, so just to be clear:
If a Chaldean rite Catholic male marries a woman who is Roman Catholic of the Latin rite, and they baptize their children in the Roman rite, the child really is a member of the Chaldean particular church?
Yes, the canon laws permit that if the father is Chaldean and the mother is Latin, and they both agree to baptize the infant in the Latin Church that the infant will be Latin sui iuris. But there is more permitted for holy days and penitential practices.
CCEO (Eastern Canon Law)
Canon 8831. The Christian faithful who are outside the territorial boundaries of their own Church sui iuris can adopt fully for themselves the feast days and days of penance which are in force where they are staying.
2. In families in which the parents are enrolled in different Churches sui iuris, it is permitted to observe the norms of one or the other Church, in regard to feast days and days of penance.
