Re: 1 week old. overfeeding?reflux? gas?
If there isn't any pain and everything else seems fine, then I woudn't worry about it. My baby spit up huge amounts constantly when he was a newborn. I had a receiving blanket draped over me at all times back then, because a burp cloth wasn't even close to being large enough to protect me from the spewing. It wasn't fun, but it was perfectly normal. Keeping your baby upright for awhile after feedings can help a little, but for us there was still copious amounts of spit up.
