At last, I managed to get a bag of sand for S' "sand pool". I had been looking around to get sand for the past 1 year, and some friends told me to get from the beach. However, the beach was a 2 hour drive from my place. Anyway, I just found out from our handyman that the hardware shop at my residential area sold sand at RM5 per bag of around 30 kg. I got a bag of fine sand and poured it into the plastic kiddie pool. He played for awhile but preferred to use a spade. He was afraid of soiling his hands. I hope he'll outgrow it though.
