This I just don't get. If I present an item to my son, on his favourite plate, there's a 50/50 chance of his eating it. If, however, I get the same item and throw it on the floor... 100% certain he'll pick it up and munch away happily. For some reason, toddlers want to put everything in their mouths. So any walk in the park, trip across town or visit to the supermarket is perpetually punctuated with me saying: "Take that out of your mouth! We don't eat off the floor". Leaves, rocks, bits of twig, squashed chips & a whole assortment of litter have all been whisked from his grubby little mitts just before he attempted to eat them. If I'm honest, there have been several times when I didn't get there quickly enough - so these items have had to be wrestled from between stubbornly closed lips. He, of course, thinks this is hilarious - while all I can think of is a potential night of projectile vomiting should he catch some lurgy or other.
A Musical Vehicle. Now I'm not suggesting that musical vehicles (like those created by Vtech) were first created by sadists in a diabolical plan to bring misery into the lives of already stressed-out parents. I'm not suggesting that at all. OK, I am suggesting that this might be one possibility.
If you think you're busy, but you still have time to poo on your own - then, frankly, you're not.
