Just the other day my toddler fell out of a shopping cart. I never paid much attention to the warning signs because I'm always right there pushing the cart, this time though I'd moved a few feet away to wrangle his older sister and he stood up in the cart. I immediately moved back towards him but I was too late. Normally he has great balance but as he reached out to me his weight shifted causing the cart to roll forward and he toppled right out. He landed right on his face in the most horrifying moment of my life. Thankfully he's all right (giant bump and a black eye) but it easily could have been fatal. I'll never leave him unrestrained in a cart again.
