Is there something wrong with this formula smell?

Formula stinks and it REALLY stinks when they spit it up. One of the many advantages to feeding in my opinion. :) If the spitting up persists ask the Dr about it when you take him in for his shots if not sooner. He'll probably be taking about 2 oz or less for the first month. Whenever in doubt call the Dr. I used to drive my Dr's crazy when mine were little but that's what they're there for! As far as cleaning, wash them with warm soapy water and then boil them to sterilize them. Don't put the rings and on until they've completely dried. Congrats and good luck with your little one!
