My recollection is your kids are in the 2'ish range with another on the way. I am curious what are the logistics for your family worship? Right now, what we do is have it as part of supper. The kids are (hopefully) already sitting down and it is not cutting into them playing or too close to bed. That seems to work reasonable well for us, so maybe tweaking when you are doing family worship would help. Now, sometimes things do go haywire and I have to cut it short or bail. And I think that is okay, and at the very least is allowing me to work on my patience. I think it has taken us a couple years to figure timing of family worship (of some sort) and for the kids to adjust. The kids evetually get use to it and our youngest (20 mon) take cues from his elder siblings. So it is a struggle but worth continuing to work at. I figure whatever we can expose our kids to, even if we do not do as much as we would prefer, God is going to bless it.
