usually 6bln keatas..bila dia dh boleh meniarap bergolek, and start makan, dh blh ajar. tp jgn paksa..kena bg support blkg dia dlu utk posture. lama2 dia akn stable sndri. xperlu rush utk bg dia duduk...kerapkan tummy time utk bg leher dia kuat...eventually dia akn mula pusing bdn and buat aktiviti2 lain
