Nowadays, Eugene is trying to stand to sit-up & stand-up by himself. Everyday no matter at his grandma's house or at home, once we put him on the mattress he will start to crawl and lean on the anything that can support him to stand up.
At his grnadma's house, the mattress will be pushed to lean against the sofa so with the sofa as a supporting, he will quickly crawled over and start to use his hands and legs to make himself stand up and then within a few seconds up he goes onto the sofa.
At home, he espically like to climb to lean against my bed and then let himself automically fell onto the mattress on the floor. He thinks this is fun and will climb up again and go repeatedly doing the same patterns. Both me and hb had a hard time trying to catch hold of him afraid that he will hurt himself but he always ended up smiling at us!
