I have just bought 蓆給 BB 蓆給 BB 車 in Mong Kok Sun Wah, it's $49.9, the brand is BABY MICKEY.They have another 蓆給 BB 蓆給 BB 車,it's $19.9, but is thinner than the other one.
I bought the "嗎口辰"席 for the baby cot last year. It costs $300-$400 in 華潤. It's highly recommended by the salelady as it's more 滑 than the traditional one. For the stroller or high chair, you can buy bamboo mat. It costs below $50.00 I've bought one from Jusco recently but I forget the price.
