New trick

I left Liam in the living room while I ran upstairs to grab something this morning and on my way back down I could hear his hurried crawl across the kitchen floors. As I took the corner of the stairs he started coming up! He had the biggest smile on his face, I didn't have the heart to stop him. He looked like such a big boy! Crawling up the stairs is probably something I shouldn't encourage but he just looked too cute! Where did my baby go?
