In addition to other answers....and going more on the colic. Some babies get colic, which is when they cry relentlessly for NO reason you can determine. My son, who is now almost 6 years old, had really BAD colic. It started when he was about 2 months old and lasted for about a month. He would scream for hours, and nothing would help. He wasn't gassy, he wasn't spitting up, he wasn't sick, wasn't hungry, wasn't wet, just unhappy as heck. We tried soy formula, we tried gripe water, nothing really helped. All we could do was be there for him and try our best to console him, and he eventually outgrew it and was back to his usual happy self.
