"When I have children"

I have three children and my parents are each remarried (my aparents, that is) so the confusion is huge. For my oldest it has been the most challenging since this all was introduced (meeting the complete birth family after we had lost contact for over a decade) when she was older. The other two haven't had a difficult time, they just go with the flow. However, they have all these people that love them and frankly, the only people they see with great frequency are my husband's family and my mom's family (amom). Everyone else is seen every few months.
