scooter-ing

I got this video after he'd already been at it for at least 30 minutes, and he was tired and ready for bed.  I can't keep him on a blanket any longer, so I've stopped trying.  When I feel guilty about letting him scoot around on our (not the cleanest) rental house carpet, Brent reminds me that Lincoln is being "immuno-desensitized" (Brent's word).
