Sunnah of Udhiyah

Should all Family Members Refrain from Shaving Hairs and Cutting Nails because of Udhiyah?

<![CDATA[Dear scholars, As-Salamu `alaykum. If the man is the one who is going to offer the sacrifice, is it permissible for his wife and children to cut their hair or nails once the first ten days of Dhul-Hijjah have begun? Jazakum Allah khayran.
