I have been lurking around the past few months, but I finally decided to join so that I could respond I am in a very similar situation as you. My husband and I have both deconverted this past year, and our children are 7 and 5. We did things differently though, and wanted to share our experience. We were heavily involved in our church, so we couldn't just slowly drift away. It was sudden. A couple of months before we left, we changed some things in our home. We stopped praying before meals, reading the Bible before bed, Bible memorization, and catechising them. We couldn't share why with them at the time, but they didn't really notice. Anytime they would remind us, we would do it, but it wasn't often. When we finally were able to extricate ourselves from our church, we explained everything with them. We told them that we didn't believe anymore, and we were no longer going to influence them. They are free to believe whatever they want to, and ask us questions. It went surprisingly well. My oldest was very sad about not seeing her friends anymore, but other than that, they have not asked to go back. I think it is a good idea to remove your daughter from AWANA's. She will only associate church with having fun. I think that's why my kids haven't asked to go back. They remember the two long sermons they had to listen to every Sunday.
I agree with the other posters about trying to substitute something fun. We have tried to do something special with them on Sundays since we stopped going. I like your craft idea. A trip to the library together, maybe play a game, cook her favorite meal, or watch a movie together are some other cheap ideas.
I would also recommend finding some science books to look at together. We have been talking about science with our kids, and they are enjoying it. My oldest a few days ago proclaimed that she had come up with an excellent question. If God didn't make us, then how did we get here? That is when my husband sat down with her with Richard Dawkins The Magic of Reality, and read the chapter explaining evolution. Her attention span wasn't quite able to finish the chapter, but she knows now that there is a scientific explanation of how we came to be.
I wish you well in this journey. It has been difficult for us. We have lost all of our friends, and that includes our children's friends too. I was hoping that some people wouldn't abandon us, but I am not holding out too much hope anymore. Just yesterday, I had to be honest with my daughter, and tell her that no one wants to be around us right now. (She had mentioned contacting an old friend.) I encouraged her to start making new friends, since she is involved in a couple of extracurricular activities. We homeschool too, so this makes it even more difficult. I did find a couple of secular family groups on meetup.com so hopefully we will make some new friends soon. I wish it didn't have to be this way, but I know we have made the right decision to leave Christianity.
