Nothing more than 10 lbs for 6 weeks. No problems first time around. Like Janine, I lifted my 3yo (25lbs+) after my 2nd csection and had a massive hernia that was finally repaired this year (which, coincidentally had a 6 week lifting restriction and Everett was 18 lbs, but Dr said he was the only exception!). 3rd csection and I followed guidelines with no problems.
I second Andrea's suggestions - floor time, crawl into your lap, Daddy time and creative standing hugs.
