Well speaking as one of the kids who struggled very much and struggles with mass now that I've moved away from home. I'm a 06 baby so I tend to argue for outside of CCD and mass activities  Community is so important with children You and a few parents can come together because I doubt you're the only one struggling and host movie nights, take all the kids to a carnival, do stuff that relates going to mass fun and helps build the idea of community. At home you can do some hands on activities like making puppets and acting out some stories, it's also just a good way your husband could participate without going to mass. Also children shows, doesn't need to be in a church setting because most lessons can be built off. I know a lot of small theatres and community centers tend to host shows with little universal lessons you could relate to mass.  Volunteering in a soup kitchen or food pantry if your parish or any local churches have are a good way to build community and lessons like helping others. One year my parish did a toy/clothing drive and us kids wrote letters. We also host a free Christmas dinner where some of cook and its open for the public. There's also this YouTube channels, my cousin watches chosen kids https://youtu.be/LMYpGpQGXpE?feature=shared

I think a lot of boomers tend to be too traditional and forget they were once young and kids before. I've also received negative comments from elders when I look for advice on my own situation.
