I would like to introduce 5 'S' tricks to handle crying baby if your baby has colic '100日哭'. I found these tricks from the book "the happiest baby on the block".

I tried tricks 1-4 at the same time, and my baby stopped crying immediately. It is quite amazing. Have a try and see if it works for your bb too.
1. Swaddle - wrap the baby tightly, including the
hands like the baby in the web site.
2. Side position - like reverse breastfeeding position
3. Shh sound - just make sh sh sound close to baby's ear (the sound that u ask people to be quiet).
