Goblin has shown sporadic interest in how his body works. I've been collecting various resources to help show him. My favourite is an excellent Usborne Flap Book 'See Inside Your Body' . This breaks down the different systems into bite sized chunks and as well as Goblin, I have learnt a lot from this book.
Another recent acquisition is a Human Body model. One of my current 'go to' bloggers An Everyday Story has a much larger version for her kids which I covet. But the big version is extremely expensive and I didn't feel I could justify the spend so I settled on a cheap smaller version. Unfortunately it means that Goblin can't really use it on his own because the pieces are too fiddly to handle, but he likes to watch me put it together and tell me what the different organs are.
InnerSpace" style journey through the digestive system (as well as through the respiratory system). Kwazi got stuck in the stomach and Captain Barnacles had to rescue him before he was melted in bile. Goblin thought it was hilarious when Kwazi reached the colon and we had to use peristalsis to poop him out.
pushes food through, pushes food through,
Pooping out the pieces, pooping out the pieces,
in the loo, we did a poo".
