Abigail will normally played at the living hall near her playmat. When she started to crawl, she crawled almost to every corner of the living hall. On the 3 Aug 2013 (a day before she reaches 7 months old), she explored the "one-step" in the house. See short clip below.
As jie jie see mei mei climbling up this one step, she also very interested to be around... see how nice to see both our princesses trying and exploring new thing every day... :)
"Abigail, Well Done! One milestone achieved!" (*I knew... I knew... mummy is very nervous seeing Abigail at the edge of the step... that is why I am your "mummy")
