I have recently had some lightbulb moments regarding myself and my DC's. I have struggled with DD from day 1, she is now 6. After much thought I have realised that I am the sort of person who likes peace and quiet, time to think, calm, order, whilst at home. I am definately an introvert.
Having children inevitably involves mess, noise, disorder, endless chatter, playdates, lots of people in the house etc etc.
If i was an extrovert i would probably thrive on the typical lifestyle that children bring with them. But i find it really hard as nearly everything to do with children goes against what i naturally prefer. I find the holidays very hard as it's full on children all the time, term time is so much better for me as I get some space and peace and quiet for 6 hours a day (although DS is not at school yet, but he's a quiet child, unlike extrovert DD).
I have a feeling that my personality will find it easier and more natural to be a parent when the DC's are much older and we can have proper conversations and they are doing interesting things at school/college/uni/work. I definately am not suited to the early years or primary school years either.
