Hey guys!

I haven't posted in a while but I was wondering if y'all could help shed some light on something. I am visiting family and one of them has a child that is 3. She can't speak very much so all she says is "mommy, tummy huuuuuuurrrrtts" and has been saying it for the last three days. This morning she v*. She doesn't seem to have a fever and she hasn't gone to the bathroom in a few days, so we were wondering if it was constipation. Does anyone have any idea what this is?

Thanks
