Active Kids = Cranky Kids

I don't know what the obsession with kids needing to be physically active these days is, but it is complete and total hogwash! We enrolled Kurtis in gymnastics yesterday and took him to the community league BBQ today and it has spelled complete DISASTER! He has been soooo tired and cranky that we are seriously moving bed-time up by as much as a whole hour, just to try and keep him civilzed. Any mothers out there with words of advice are welcome to give us ideas :)
