Help

So long story short, I am a SAHM and have stress fractures in both shins. I technically can walk but I absolutely should not be walking.

My 18m old son is used to going on outings basically every day. Baby groups, stores, park, etc. I can't do any of it. I can't even pick him up to put him in his car seat.

He is beyond done with this whole sitting around at home doing nothing thing.

Please please please, does anyone have any ideas of things I can do with him that don't involve me having to stand/walk? What are your toddlers favorite toys and mess free activities? Favorite books? So far reading has been the best thing but him and I are both getting tired of our books (we read Llama Llama hide and seek on repeat for an HOUR yesterday).

I just really need help coming up with ways to keep him happy/entertained that allow me to be couch locked. I really don't want to do TV unless I absolutely have to.
