Thanks for your assurance, LovingRadiance 
I am also quite confident that we are able to go on being honest to ourselves, each other and the children. So, although they will notice their family is different, they won't be bothered about the situation. In fact, I grew up in a similar, poly-like family situation and I can't say it did me any harm, nor did I ever feel ashamed about it. Quite the opposite: the way my parents handle their relationship and their relationships with others (lovers and friends) always impressed me, and I must say I am really proud I grew up in such a cool family. I have some hope that our children think the same one day (even if they might not admit it to us
).
