I've got 7 month old twins and I worry that I don't do enough with them. We live in an area of tight covid restrictions so can't do that much anyway. We live on the edge of a national park and have lots of walks, but outside of the house that is pretty much it. I'm conscious that as the weather changes we will probably be out a lot less.
At home, when the babies are not eating or sleeping they spend almost all of their time rolling around on the floor. They've got a big box of different toys and I try to get different ones out each day. They've got a door bouncer and a jumperoo. They like me singing to them but don't want to stay still to look at books. They seem to much prefer playing on the floor independently than when I've tried to do things with them. So I largely just watch them play (and try very hard to crawl) by themselves. They can't sit by themselves yet so I spend time helping them practice that.
Is this ok?? They seem like pretty happy little babies but I feel a bit lazy spending a lot of time watching them rather than actively doing things with them 
Am I overthinking this? If not, what else can I do with them?
