So when does discussion become competition?As Evenhope says, if you child did something early or is very good at something, it doesn't matter if you just state the bare facts, somebody is going to take it the wrong way sometimes and assume you are bragging. But surely that becomes their problem, if they always want to be one better than you and your DC and can't simply accept their children for what they are.
I like discussing the achievements and failings of my children and other people's but I am not doing it see if I can give my children the advantage as such, it isn't a race for my children to beat other children at. It is just a case of me being interested in the way that children develop. Isn't that what Mumsnet is all about - sharing experiences? For example, if somebody can share with me a way of helping me teach my DC their times tables, I could take that as them bragging about their children being good at their tables or I could simply take it on board as useful advice.
I suppose it is often a question of perception. But then in other cases like, Morning Glory's cake example, where somebody is literally lying to look good then you have to ask what is the point? Why does it matter so much?
