Six or more wet diapers = not dehydrated. My second to youngest was not a pooper, and she threw up (not spit up) after EVERY meal. I did eventually have to switch her to formula, because with the stress of 4 kids (at the time) and my husband being deployed, my milk ended up drying up.
As for the chapped lips, are you in a dry climate? It might just be the changing of the seasons. But I do agree, call the doctor and talk to him/her before rushing to the ER.
