Oh, yeah. When you come home from work, make sure you change your shirt before you take the baby. He will be spitting up on you and that stuff stains.
Burping after every feeding is critical to minimizing the chances of colic. They swallow a lot of air, and if they don't burp, that air bubble causes them great pain.
Babies can breathe and swallow milk at the same time. We lose that ability after about the first year, I think.
If the baby gets colic anyway, and all else has failed to calm him, strap him into your car and drive around for a few minutes. Works every time.
