My dd is 19 mos. and has for the most part always sat in a cart well. I do still take my sling along everywhere and if she isn't wanting to sit in the cart, I put her in the sling (she's about 22 lbs. so it's not really that hard to still wear her). She is absolutely not allowed to run around in a store. Too many things to get hurt with. If in the store, she wants out of the cart, I either put it aside and run out to get the sling, or we leave.
Is it normal toddler behaviour to want to run around in a store? Of course it is... new exciting place to explore! Perhaps if you took something from a shelf and gave it to ds, it would keep him occupied? My dd loves buckling and unbuckling the belt, so that keeps her for a good 15 minutes at least. She likes to be whispered to, so I whisper in her ear as we roll along and tell her about what we're doing. And peek-a-boo under the cart handle (even though she can still see me) is fun. We look pretty goofy in the store, usually, but she's never had a tantrum in public.
HTH!
