Adrian didn't really 落水 yet. He just soaked his legs (upto pat pat) into the water. I am quite surprise. He wasn't scare at all, he even wanted to chase the waves and walked out to the sea tim (of course he couldn't walk lah).
Actually, I bought 3 items from Sanrio at Sogo, one set of arm band, a float boat with steering wheel and a normal swimming ring. The 2 holes of the float boat are quite small although it's ideally for age 3 & up. I think it's ok if the baby is under our supervision. For your info, the diameter is 10cm before inflated. I wanna to upload the images for you to have a look, unfortunately I could not managed to do so. Sorry!
