Attending service as a family and family activities

Hello Nicholeen, I hope you're well. I would like to ask your advice on how to communicate with my spouse about the importance of worshiping together and putting family activities over children-only activities. Our church has Sunday school for children during our regular service, but I would like to keep all my children in service with us, so we can worship together. I believe that training them to listen to the sermon and singing and praying together is good for family bonding, and strengthens our relationship. I know they won't pay attention all the time, and some things will go over their head, and that is ok. I sometimes get distracted too. He says it is good either way, but that the kids will miss their friends, that the children don't get many opportunities to see their friends, except for Sunday school, or activities that the church puts together for children. I think they can socialize before and after service. So, he's not against it, but he says that when the children see their friends going to Sunday school and not them, then I have to explain to them the reasons and deal with it by myself. 🙁
I had also mentioned to my spouse that I would like to minimize activities outside the house where the activity is just for a specific age group and mostly withouth parents. So, our church organizes various events throughout the year, but they are usually just middle schoolers, or just for high schoolers, where the parents drop them off and then pick them up at the end of the event. We have children in elementary, middle, and high school, so we would have to separate the family. I do like attending events where the whole family is included, but not so much when the children are separated from us and the rest of the family. I can see that happening more when my oldest turns 16 or so (he's 14 now). My husband doesn't see anything wrong with it. He says the children need socialization with their peers and that they should go, especially because these are activities organized by the church where the parents are Christian too. My spouse is a very social person, so I understand where that is coming from. I do agree they need socialization, but that we get to decide who they socialize with and that we are there too. Unfortunately, the fact that we all go to the same church doesn't guaranty that we all have the same standards.
What do you think, Nicholeen? am I being extreme? your insights will be very helpful. thank you!
