HX update-6 months old

Too overwhelmed by the locked car incidence and have forgotten to update HX progress.
At last follow up at Klinik Kesihatan, her weight is 6.6kg, length is 66cm ( increased by 4cm after last month).
She also grows a tooth, ya only a tooth from bottom. I am not sure if this is normal, as usually it should be 2 at the same time. Somehow HX tend to have one side different from another, be it hair, eye, dimple. Hope its just that.

Also, she started crawling since 5 months old, now she know how to sit up.
