我個女now is 6years old, her 100th day, my mother 都係咁做, 佢15個月先出牙, mug都冇事發生, 出得好舒服. My son now is 4months old, his 100th days, my mother did it again. Recommend!
I did it for my son on his one month birthday. He never gets fever becox of teething. Maybe it is scientific as the material of 9 vegatables may sooth teething pain.
