We practice liturgical worship in a traditional style.
Our Sunday morning worship services are almost always one of the Divine Service settings from our main hymnal, Lutheran Service Book. Once in a while we will have something not out of the hymnal. We don't use a praise band. We don't use an overhead projector. We use organ, piano, or guitar to accompany the singing, and we aren't afraid to sing a capella (just voices). During the church year seasons of Advent (four weeks before Christmas) and Lent (seven weeks before Easter) we also have Wednesday services that are shorter and less formal.
God is holy, yet merciful (because of Jesus). We worship this holy and merciful God through worship that is orderly and dignified, as befits His nature, yet also joyful and humble. We seek to avoid the twin extremes of stuffy-ness and showy-ness.
Do bring your children! Even the smallest child is capable of saving faith, and Jesus said, The kingdom of God belongs to such as these (Luke 18:16). The repetitious and predictable nature of liturgical worship such as ours is the absolute best way for children to learn about God. Assemble the people, God commanded Moses: men, women, and little ones, and the sojourner within your towns, that they may hear and learn to fear the Lord your God, and be careful to do all the words of this law, and that their children, who have not known it, may hear and learn to fear the Lord your God (Deuteronomy 31:12).
