Phillip learned to go crawl up the stairs last month but we were still working on going downstairs go I couldn't call him a "master" yet, but this week Phillip would crawl up the first step, and then step back down all by himself. Both he and I are so proud when he does it. He hasn't officially gone all the way up and all the way down by himself but there are 13 steps and he's only 10 months.I am so proud just to see him practising the stairs.
