I reread my last post and noticed a large mess up. I definitely think Sunday family fun day is great....and do it as long as you can. Ours was Wednesdays....Lasted for a few months, but my kids are older. So eventually they wanted to do their own thing and the Wednesdays ended.
Go with the mommy instincts....They rule. (yes I am jealous of mommies and their instincts....Just can't learn it myself).
