This is a great idea and could make all of the difference in the world in families feeling welcome! Tell them to bend down and greet the children at their eye level, most adults don't do that an act like the kids aren't there, just talking to the parents
This was done at my last parish, and several of the greeters/congregation do it at my current one. It makes a world of difference.
I have seen the things pmcleanj, higgs, chalice, timothy, etc, have mentioned in this thread applied in two churches. My former parish started out a dying parish (actualy 2 dying parishes that were combined into one, and that one's fate was uncertain). These changes were made and the congregation became intentional about them. The church is now a growing, thriving, spirit-filled place where even some of the most staunch older members of the 'old ways' now agree that it is a good thing. My current parish is in a transition, somewhat divided, with a little over half making these kinds of efforts. The under-half portion that chooses to "glare" at mothers with babies and shush children and parents out of church over minor disruptions have successfully done so. None (other than ourselves) have returned after being exposed to that sort of treatment. It seems we need 3 welcoming, supportive people for every 1 crotchity old bag, or we lose the would-be parishioner.
And -- what happens next:
Someone turns and glares at you and maybe even pointedly informs you that there is a nursery
~or~
Someone leans over and whispers how wonderful it is to hear children's voices in church and smiles at you?
Which scenario would cause you to leave the service in tears and forget about going to church at all?
Oh, the memories!
I remember when we first moved to our current town, and started attending our current church. My daughter was 19 months and my wife was almost 8 months pregnant. Our first visit, we got a look of fright as we brought our daughter into church - during the summer, when there was no sunday school! How dare we! The second visit (the following week), we were told that it was nice to see children in the church, unfortunately they make it harder to hear the sermon. On that particular day my daughter had been rather silent and still, the only noise she made was flipping through the prayerbooks, pretending to read and follow along like the adults. Aparently, the sound of pages turning was just too much. On the way out I was walking a little ahead of my wife in the parking lot, turned around and saw her crying, and she said she just really missed our old church. That day sucked.
I've always wondered what these people would say if you could actually show them the numbers - the actual people - that have not returned because this kind of treatment. If you told me, "that person over there did not come back to church because you scowled at them," I would be mortified. I might be extremely annoyed with that hyperactive, undisciplined, wild child and the parents that don't appear to care; or that baby sitting behind me that whines and cries whevever its mother sits down; however, what a horrible thing it would be to chase them out of church with glares, scowls, or directions to the nursery/hall/outside. I know from experience that MOST of those mothers, parents, and sometimes even the children, are there in the sanctuary - disturbances and all - because they're looking for support, and/or for a supportive worship community.
