Our boy is better!
He finally got over all of his sicknesses:
sores on his bottom from diarrhea
many, many, many baths, but still got 2 sores
Yep, these were all happening at the same time. He has 2 upper molars coming through his gums right now, and still none on the bottom. He has started with some yucky diapers again, and I think that this time it is teething ONLY! :)
