Milestones--We have a crawler

Colin started really crawling last night. He's been doing a couple crawls together, but he did about six movements together last night, and did even more this morning. He seems to know he's got it figured out, so I'm guessing once he gets really good at it I won't be sitting down for the next year. He'll be into everything. Last night he was throwing a fit in the living room while Scott and I were cooking dinner, so I brought him into the kitchen, sat him on the floor, and gave him a plastic bowl and wooden spoon. He found it great fun...that is until he fell over after about 8 minutes and hit his shoulder/head against the floor/cabinet? He was okay, but it scared him. We will have lots of falls to come once he begins to cruise and walk, but he seems pretty tough.
