Daughter's 1st birthday

Our daughter had her 1st birthday last week . For Koreans and many other Asians the 1st birthday is very important. It must be celebrated on for before the day but not after the actual birthday. She is wearing the traditional Korean dress ("hanbok"). It was good to be able to celebrate her birthday with family here in Australia but it would have been nice to be able to share her birthday with our neighhours in Thailand and see what customs surround the 1st birthday there.
