School preparation or lack thereof

I can't believe my eldest son starts kindy in 2 weeks! And I also can't believe how unorganised I am for the whole thing. It (being unorganised) is making me feel like a bad mother. I was always going to be one of these mums who has all the 'i' 's dotted and t's crossed well before my baby started school for the first time. So what happened?! Why didn't I get my bum into gear and get everything sorted. I could make all kinds of excuses, but really they're pretty lame. Especially when this is my first ever child embarking on a life changing journey and I've done pretty much nothing. A friend visited recently and was asking W about school. She has young children, one who started kindy last year. W told her all about his new drink bottle and lunch box, so she excitedly asked him what else he has bought for school? New shoes? He shook his head. New books? He shook his head. A new uniform? Again he shook his head. Thankfully she took the cue and stopped asking, saving me further embarrassment.
Ok, well I've got his book list filled (pencils,crayons etc), bought 2 shirts in school colours, got a backpack and grabbed a lunch box & drink bottle on a spur of the moment, but THAT'S IT. I always imagined that I'd take my child on a shopping day out so he could excitedly choose all things needed for school. But no, I grabbed things on a whim whenever I remembered and then showed him later when I got home. Of course, he was SO excited with each presentation of school-related item, but I felt guilty as hell that it was all bought last minute and without ceremony.
Thankfully, W loves the things I've bought him and doesn't realise that they don't match or that he should have been with me to choose them. The innocence of a 4 year old! Maybe when he eventually does the big move to Year One I will be the Mum I always thought I would be.
