Have you ever read or seen the DVD by Dr. Harvey Karp that is called the "Happiest Baby on the Block"? It was a lifesaver for my hubby and me with our first son that a neighbor recommended to us. Tomorrow I am having our second son and plan to use it again. As long as your son does not have any medical issues, it works like a charm! Here is the "Five S" sequence he teaches, but I highly recommend that you get the book, or DVD too.
1- Swaddle (super tight!!! Remember he was even tighter in your womb, he will feel secure.)
2- Side or stomach (while holding him, NEVER to go down to sleep)
3- Swing (from side to side in your arms, fast)
4- Shhhh (the louder he cries, the louder you say shhh in his ear until he calms down. It reminds him of the womb sounds. Those Womb Bears work great too!)
5- Suck (nurse, bottle, or pacifier)
That should calm him down and once he starts sucking, it will take him off to dreamland. Try it and see if it works for you. Hope this helps!!! Please let me know if you try it. My mom-in-law, who is a super baby person, could not believe how well we could calm our newborn as first time parents. =)
P.S. We co-slept for the first year and I highly recommend it too. The bottom line though is that you need to do what feels right to you. Please do not hesitate to contact me with any questions you may have!
Best of luck!!!!!
Smiles!
