So my sims daughter is married and has two children but when her parents come over and they cuddle the baby or toddler it doesn’t show as their grandchildren. Also when your the mom and click on the daughter it doesn’t show as daughter anymore either. They have a two sons also who’s both married with one child but when their parents cuddle their toddler and be nice to the teen it shows as their grandchild. One of the sons took their wife’s last name as well. What’s really going on?
