I took the photo at home
What I did was to put the white cloth diaper on the bed as background. Then I place my boy on top of the white background. Make him smile then take & take & take. Took around 20 pictures (all awake, but some not looking at cam, some blur, with flash, no flash etc etc). Then upload onto computer, choose the best one, crop according to ICA guidelines. I submitted online, so there was a part where they ask you to upload photo then adjust according to their template (where the top of the head must be, wear the shoulder must be, etc).
Quite easy to do If you take those instant type, sure waste alot of money if the photo is not approved cos it's hard to take photo for babies!
