First time crawling position

Masa ni irfan first time in this position. At first, macam tak selesa jer, but lama2 dia stabil dah.
When he was 4 months old, bawa g clinic for immune, that time his weight was 5.4 kg. Dr kata OK, but quite small for a boy. Nak buat camner, mother father dia pun tak ler besar sgt. Especially if follow his grandfather's generation.( Hj. Lop's generation).
