I find that I judge more when I am being judged. If another parent is not being nice about my parenting, then I will tend to find fault in them. I have to admit early on I was quite judgemental, but as my parenting time has increased I have become more understanding of different parenting and as such tend to judge less, or maybe it is more that I am better at not letting things affect me. Also now I tend to keep any judgemental thoughts to myself, well most of the time, I can be nasty when I am in the mood.

I will admit something shallow, I will be more judgemental of someone's parenting if I just plain don't like them for some reason
