It's 3 a.m. and your baby is screaming like a banshee. You and your partner have no idea what to do. You want to call your mom, but she's sound asleep at home so all you can do is cry.

Don't let this happen again. Watch The Happiest Baby on the Block DVD ($22) by Dr. Harvey Karp. You can buy the book too, but seeing the tactics acted out is more educational. I did both to be doubly prepared.

Dr. Harvey Karp has been a practicing pediatrician for over 25 years. He began studying colic back in 1981 and has come up with his own method to calm crying babies. He preaches the five S's — swaddling, side/stomach position, shushing, swinging, and sucking. He believes that using one or a combination of the S's activates the calming reflex in babies.

I am a believer — we shushed, swaddled, and swung like crazy people. Sucking was popular, too and the side positioning came in handy occasionally. Our friends told us to get this DVD and I flinched at the price. If you don't want to buy it, check your local library to see if you can check it out. It's a lesson worth learning. You'll want to be armed with the S knowledge when you bring baby home from the hospital.
