Actually 1 year old is a bit special, other years might be not that special lor!
I made a birthday party for my girl when she was 1. We spent a lot of $$$, buying huge cake but she had totally no ideas on it.
After that, I booked a hotel room in Disneyland Hotel to celebrate her birthday, let her play play play and eat eat eat with Minnie. She enjoys a lot...... so, I am going to organize a party for her until she requests lor!
This year, I brought a huge birthday cake to her school on her birthday and let her celebrating it with her teachers and classmates, she loved so much!
