My DD (3 and a half) has told me a few times that when she strains to poop she hears airplanes. I didn't think anything of it at first, but then I became worried that perhaps a blood vessel in her head is not right or something --actually I don't know what I am worried about, I'm just worried! I asked DH if he ever had this experience and he said no. I've never heard anyone say anything like this before. SHOULD I be worried?
