Gar Gar's milestone (part I)

Gar Gar is coming 6m old and he has fully mastered the skill of flipping over n back recently. Now he is very good at it. He could now do the "zhenzi" style crawling like what his gor gor used to do. Altho he is a little hmmm.. Overweight, his crawling speed does not lose out to gor gor! So mummy n aunty is keeping an eye over him in case he overdo it n knock his head like the big head monster! Gar gar, u r still a little behind time, u should b sitting by now, ok?!
