Niece's birthday Gift

Next week, is my niece one year old. No idea what to give him as a birthday gift. He already had a lot of toys. At first want to buy the small swimming pool as he likes water, let him swim at his house’s garden there. But heard that his uncle who staying in Singapore already bought to him so I have to think again. I am asking around my friend and colleagues, they gave me the answer is like that give him Ang Pao (money) more reality.
