My dd is 3 in December and lately when she needs to poo she always says her tummy hurts. I do not know if she just thinks the sensations of needing to poo is her tummy hurting....or if there is something else going on. She poops once or twice a day. Lately it is a little mushy. But she also just started nursery and eating lunch there daily.....so not sure if it is change of diet causing slightly mushy poo. Or could it be a bug? She is fine after she does her poo, eats normally etc.
