One thing that can show Vikings didn't find children important is that if the new born was unwell they would send them out in the ocean where they would eventually die. However, they did give babies a Thor-hammer charm to protect them from evil.
This is a model of the Thor-hammer charm that they gave the new-born's to protect them from evil.
Boys would often take their father's name. So Loki the son of Tori became Loki Torison. One the other hand, girls would also take their fathers name but use daughtier t the end not son. So Bryhild the daughter of Tori becam Bryhild Toridaughtier.
Over all the life for an Viking child wasn't very pleasant and they didn't have much of a significance in the Viking life apart from doing their housework.
