Hello M.! I do not live in Olathe and my kids are now almost 7 and 9. But, if you haven't thought about it, I would suggest looking into a Mom's Club. I was in one when my kids were younger and I believe there's a Mom's Club of Olathe. I loved this, the club I belonged to had monthly "meetings", weekly events (usually 2-3/week) that someone else planned out and we could attend what interest us, and they had individul playgroups within the group.
It sounds like it might be just what you need. It can be a challenge, my kids were handfuls as well, but I cherished being able to stay at home with them. Now my youngest is starting first grade and it will be an adjustment. Good luck.
