What to do when baby cries:
1. check if baby is hungry
2. check if diaper is soiled and needs to be changed
3. burp the baby
4. check ventilation of room and baby's clothing; if too hot or cold
5. check if baby is bored/needs attention (try talking, playing, singing)
6. swaddle baby and plays the white noise CD / mozart music
7. carry and cuddle baby
8. check if baby needs a bath, followed by massage
9. check if baby is not feeling well (fever/cold)
10. at the last resort, give pacifier

I learnt something new about swaddling - that it keeps baby stay calmer and sleep longer when wrapped with the arms down at the sides. It's recommended to swaddle baby during the sleep period only (nighttime or nap time). Snug swaddling also reduces a baby’s mobility and may help keep babies from wiggling into a dangerous situation. It's okay to swaddle baby until they are 5-6 months old.

I also learnt about baby's first white noise. These are sounds that helps to calm crying or fussy babies, ease colic or sooth baby to sleep through the night.

I was quite enthusiastic. I called up Borders Wheelock Place and check if they carry The Happiest Baby book/dvd/cd. If they have, I'm going to buy tonight after work. Unfortunately, this book is out of stock and they are not sure whether they'll be ordering and if so, when it will be in stock.
So within minutes, I login to my Vpost and placed an order with Amazon.com! I'll also buy the swaddle blanket later at Spring Maternity. (organic Swaddleme $58, normal ones $30+)
