In In re Anthony P. (1995) 39 Cal.App.4th 635, the court held that "appellant has waived her right to assert error as to sibling visitation on appeal by not properly raising the issue below. No objection was interposed in superior court premised upon: the alleged failure to 'maintaining sibling togetherness and contact' ( 16002, subd. (b)); the purported failure to 'provide for ongoing and frequent interaction among siblings until family reunification is achieved' ( 16002, subd. (b)); or the supposed failure to state reasons for the suspension of sibling interaction. ( 16002, subd. (c).) Hence, any objection to the absence of an order providing for sibling visitation has been waived." ( Id. at p. 641.)
