Michelle - in case you check back - people are rarely hospitalized for pneumonia anymore overall. C. - in case you are worried about that - it's better he be at home anyway - there are FAR more germs in the hospital than at home!
My question is - is he on antibiotics for the pneumonia? If he is - make sure he's eating yogurt with LIVE cultures in it. Antibiotics strip the body of certain bacteria and the yogurt helps replenish them (but the live cultures are necessary). Stonyfield makes great organic yogurt with live cultures and no additives like aspartame.
BUT - antibiotics can also create a condition called Thrush - it is a yeast infection that grows in the mouth and/or throat. Look in his mouth - if you can! If it is bright red - I mean bright red, or has white patches - it may be thrush. The MD can check also - there is a nystatin wash that they can give you for it. But - if he's been on antibiotics - that may be what's causing the sore throat. Thrush can be very painful.
Good luck to you and your little guy!
