If you are under 26, YOU can be on your parent's plan but your spouse and children can not. Your spouse could be on her parent's plan but you would need something for the children. Like said above, you can get coverage through your school, just price out plans on the exchange, medicare and the school policy to see what is the most reasonable, including out of pocket costs! I just looked at my in-state plan, it's $1100/month for a family plan, YIKES!!!
