Bayside is wonderful, and so is Adventure Christian in Roseville. You have the option of using the nursery/childcare if you want to be able to focus on the service and get a little break, but by no means are the children not welcome in the main auditorium. It is totally up to the family whether to use the children's program or not. I found that once my son was around 3, he got a lot more out of the children's program than the main service (they teach them Bible lessons on an age-appropriate level). He liked to play, run around, not have to be quiet, etc. and he was bored in the main service once the worship and singing was over. What I would often do is bring him in with us for the beginning of services and the worship, then if he started to get bored or restless, take him over to the children's program. Adventure has separate classes/rooms based on age, so infants are in their own room, toddlers in another, two year olds, three year olds, etc. all the way up through high school, but it is NOT mandatory, it's for the benefit of the families and kids that choose to make use of it. Best wishes finding a church home :)
