A little too much...

I had a c section last Friday the 22nd so it's been almost 2 weeks and I feel great, but I think I'm doing a little too much. I'm at the park with my newborn and 3 year old and I've been lifting the stroller and car seat and picking my 3 year old up. Im sore now and I'm worried I did too much. Anyone else with c sections doing a little too much or do you think I'm fine with what I'm doing? This is f section number 2
