When my son was about 3 weeks old we went to the Merry Hill centre for our Christmas shopping. It was getting busy by the time we left and I was carrying him back to the car while my wife pushed the pram with all the shopping in.
As we were walking through the car park is felt wetness on my top. At first I thought maybe he'd been sick, but then I smelt it. He'd had a explosive poop, out of his nappy, through his vest and sleepsuit and onto my clean white t-shirt.
We had to change his nappy in the car while people were queuing for parking spaces, getting rather irate that we weren't going anywhere.
Oh the joys of parenting, wouldn't change it for the world though :-D
