It's something I've always wondered!
The constant boundary-setting for a little one makes me think that being a parent of a 2 -5 year old must make you more likely to be able to transfer these skills to adults, e.g. if you need to speak up for yourself when out and about, in the workplace etc.?
Is there a point now where it's so much easier than it was before you had children, or you just don't care so much about trying to people-please?
Maybe I'm being too optimistic - I'm very shy myself but always thought that I would be a bit more outspoken once I had DC because they would be the focus and I wouldn't be as self-conscious anymore. Life would be too short! Am I right?
