We attend Spring Baptist Church in Spring, North of town. We love love LOVE our church, mainly because of its love for children. I have 2 boys, 2 1/2 and 9 and they love going. My 2 year old wants to go to church and friends everyday. For me the benefit of the child care while you are in church, the difference from the normal weekly day care, is that these people are volunteering to be there, and they are there to teach your child abou the love of Christ. The workers at our church are amazing in this way. They truely LOVE the kids and the kids can tell. These are not people who are there for a paycheck, who come sick, who may or may not be qualified. These are moms, dads, and grandmothers who are there because they want to be.
But to me the thing you have to think about is what your daughter is learning from you right now. This is the age where they mimic and watch you constantly to see what is important and normal. If you take her to church and show her that is important, if she sees you reading your bible or working on bible study homework, if you listen to praise music in the car with her, and show her that God is important in your life then she will know that this is a normal part of life. Later in her life it may not be as easy to integrate.
Also I thought I should mention, my church also has AWANAs and preschool chior starting at age 3 and the kids love it. VBS is held every summer for those going into kindergarten to leaving 5th grade, and they do it up right, it is an awesome week. Once the kids are in 3rd grade there is a camp in the summer that I have heard is a lot of fun, we will go our first time next year. There are fall festivals at Halloween, Round Up Sunday with all kinds of fun things for the kids in February, and many other special days through the year.
I hope some of this helps. Good luck.
