After realising she is OK, we are not so worried anymore but knowing her new-found skill of being semi-mobile, we have to be very carefuol from now on. Just today, after realising that she can roll to her stomach, she is now trying to crawl. Which is a very exciting event for her. But after a few minutes of trying (clawing), and realising she is not going anywhere, she cries.
And now, she is only happy when I let her stand on her feet (with assistance, of course). Sigh, this means that she wants to skip the crawling part and prefer to walk instead. Look out, World!
