I'm sure I'll be in the minority here, and old fashioned to boot. These are just my personal opinions of what has worked for us, not something I can give a scripture quote on.
Some places we lived those little old grandmas taught the gospel clearly and effectively, but the preacher was, to be kind, lacking in Biblical knowledge. In those places, rather than cause a stink we went to SS and home, or, if there were another church with a poor SS but excellent preaching service, raced across village to the other church for preaching.
We were always of the opinion the children needed to be in church services with us. Sometimes that meant sitting way in back and sneaking out to feed a fussy baby, or taking a toddler out for a discussion of proper behavior. It did not ever mean older kids and teens sitting with their friends.
That also meant seeking churches with services that were reasonable for families. Pretty much limits the time to around an hour to an hour and a half. I don't think we older ones are adhd, but you might, because if you cannot say what you have to say in 30-40 minutes chances are my aching hips and numb ears aren't going to let me hear what you have to say anyway.
We also find the hymn sandwich style of worship worked best with little ones. Doing everything (sing, pray, listen to preaching) in sets or blocks didn't work for us.
We chose churches that figured Sunday mornings were preaching/evangelistic. Sunday nights were for discipleship and equipping the saints. Wednesday night prayer meeting was just that--praying. We attended as much as we could but were not dogmatic. Common sense intervened at a few times.
That formula is hard to find these days, so we do what we can. We attend those programs that fit into that format and just skip those that don't. With no training union or discipleship training at our church, we study independently or in other Bible studies.
I've always been a firm believer that IF a pastor is preaching the scripture rather than sermonettes for Christianettes, and IF the congregation takes their role seriously and studies also, it is safe to let someone other than the preacher teach. Those grandmas should know the truth when they teach SS. Those youth leaders should know the truth when they meet with the youth.
In other words, we avoid like the plague churches where the pastor is seen as priest or guru. We believe in the priesthood of the believer--singular--as a safeguard against heresy and false prophets.
Not everyone's cup of tea, and that's ok. Just how its done at our house.
