And while we're talking about Apollo, the second round of antibiotics seem to have done the trick. He is much better. His cheeks are still a bit red and scratchy, but are looking much better as well.
The only remaining problems are his sleep and weight gain. I weighed him on Monday and he was up an ounce and a half. Yay! I weighed him yesterday and he was back down that ounce and a half. He still weighs less then he did at four months and only nine ounces more than he did at three months.
He lost weight when he was sick, of course. And he is a very, very active baby, so he burns a lot of calories. Because he isn't gaining weight though, I am nursing him frequently at night. Like every time he wakes up, which is at least every two hours. If he doesn't start to put on weight soon, I'll be taking him to my midwife who is also an Naturopathic doctor and see if she has any suggestions.
