i googled to find when to change passport photo for toddler but couldn't find any.
hadzim had his own passport when he only 2 months++. see the photo above (ok, kelakau muka dia masa tu hihi). masa tu nak balik raya singapore so kene laa buat passport. this year nak balik raya singapore lagi, and hadzim already reached 2 years++. maka haruslah berubah muka iteww. so sebelum kene membebel kat officer kat causeway tu maka lebih baik tukar gambar dia sekarang.
actually there is no exact period when you have to change your toddler's photo. masa tanya kat officer to he just said --- no exact period of time, you can change your photo whenever the photo (appeared in your passport) has significant different from you current face. and oh, no charges charged.
rasanya next kene tukar photo when he reach 4 or maybe 5 laa kot. tapi masa tu dah renew passport baru dah plakkk so mmg harus kene tukar gamba :)
