What is this? Foreign object in baby's poo? (Sorry there's a pic)

[zinch]

I've scribbled out the other normal poo as it's just not nice to look at.

What is this?? It's bigger than a kidney bean, sort of like a big grape.

I keep expecting my brain to go, oh THAT'S what it is! But there is nothing he's eaten that remotely looks like that.

I thought aubergine, but he's had none. I thought kidney bean but he's only had one Ella's pouch which was mild chilli and I'm sure it didn't have giant lumps in it, plus this has a sort of rubbery skin like texture, much the same as aubergine.

I'm so confused, and hoping it's not from inside him. Wtf! Anyone got any ideas?

Pics (sorry in advance)

Gosh. Could be a piece of red kidney bean from the ella's pouch?

Or maybe a piece of apple/peach that was swallowed whole - the skin would probably discolour like that on its journey through baby's gut.
