Lo is 22 months. 2 weeks ago he started with a tummy bug, only sick twice but lots of loose nappies. It went on for almost a week before the bug seemed to have gone. Then after 5 days he started with loose nappies again and has since had at least one every other day. What could be causing it? Should I contact the gp? He's still eating as normal and drinking plenty. He is having tummy pain on and off and lots of wind. Thanks.
