Could someone please help me with a pooh related enquiry

[Jemli]

Every so often my son pooh contains what i can only decribe as black sand. I am certainly not feeding him that and cannot think of what would cause this. Has anyone else had the same experience so that I can prevent it happening again. Many thanks in advance for any suggestions

How old is your son? Hes not eatting mud/soil is he??

My DD has been caught tucking into the soil in my large pot plant a few times!!

Might be caused by eating bananas, it may be the seeds.

Was just about to say blueberries- they have tiny wee seeds. Or strawberries.

Might he be teething? My daughter and son both had gritty pooh during teething, some of which was dark, depending on what they had been eating. Otherwise, how about kiwi fruit seeds? Or raspberry pips?

Thanks everyone... these are all helpful suggestions (although he is only one so not tucking into mud pies yet). Yes he did have a banana the day before and has had one today, so I guess i will know tomorrow if that is the culprit. How does teething cause this effect?? He has six of his front teeth through, but I think maybe the back molars may be on the move. I have noticed him chewing a teething toy at the back of his mouth, but i struggle to get him to open his mouth long enough to see what is going on.

Jemli- My DD has just turned one and like I say.. has been caught munching soil from the pot plant!

Jemli, I'm afraid I have no idea why teething causes gritty poos, but it was something suggested to me and it seemed to fit the facts at the time. Another possibility, I've just thought, could it be pears ... at least for the grittyness?!
