It is 5.30 in the morning. BAM! The bedroom door is flung open. Flap, flap, flap. Little feet cross the room towards my sleeping form. 'Wake up, Mummy,' a little voice demands sweetly. But this is the Trojan Horse of sweet voices. It bears into the room a force to be reckoned with. 'Mummy is still tired, darling,' I plead hopelessly. 'Why don't you cuddle up next to me?' My heart sinks as a determined little face thrusts itself at me. 'But I want milk and I want TV and I want breakfast.' And I know I have a Bad Kid Day ahead of me. Just like its namesake the Bad Hair Day, the Bad Kid Day starts from the moment you wake up and whatever you do you will not shake it off. Like the hairdo that will not lie straight or part in the middle no matter how much you coax it, the pre-school child on a Bad Kid Day will not bend to your will, or be swayed from its path of obstreperous behaviour. In fact, just like hair, the more you fuss the worse it gets. Who knows what makes them wake in such a temper? Maybe they make a decision at the beginning of the day and just tenaciously stick with it. Or watch you before waking you and deliberately choose the days when you are sick or hung over to really go for it. One thing for sure, your mini Jekyll and Hyde will always start the day as it means to go on. Days and days of perfect manners and family harmony are forgotten entirely after one day's visit to the dark side. Every process from cajoling, pleading or threatening your three-year-old to getting dressed in the morning to dragging her kicking and screaming into the bath at night becomes an epic battle. You will need at least the guile, negotiation skills and patience of Secretary-General Kofi Annan on a particularly tough day at the UN. You are never truly a parent until you are counting down the seconds until bedtime. But when the golden hour chimes the apple of your eye has other ideas and how do you get a reluctant child to sleep? How do you brush a child's teeth when their mouth is clenched tight? The word 'no' seems to get out without a problem, without leaving any room for a toothbrush to get in. But then the next morning I will wake up and a soft little mouth will be giving me butterfly kisses. 'Can I cuddle up with you, Mummy?' she will say as she scrambles to fit her warm little body around the curve of my back. 'I love you,' she will murmur as she drifts back off to sleep. Bad Kid Day? What's that?
