I second the advice about taking the initiative to start conversations (even if you feel uncomfortable), and to join small groups and service groups-- it's easier to talk to acquaintances, IMO, if you have a given subject to talk about already, such as the project you are working on together.
Another thought-- at the coffee hour, if your family is all introverts-- do you sit together in a group? If so, other people may see you as a group which is self-sufficient and not welcoming, not engaging. Maybe you could take one kid and tackle another mom, and let your DH take a kid and tackle someone else.
Well, not tackle, but engage in conversation.:001_smile:That's what I meant.
