Ronny's worming tablet didn't produce anything. We'll take him for another check on Monday, to see how he is going. At this point, mum is finding it hard to see the situation clearly so needs an outside eye to watch his progress. He is still playing though, and likes being involved in anything that is going on. The vet said there wasn't much point in seperating him from his siblings, as she didn't think it was viral, and that if it was, they had had a lot of exposure already anyway. From what we understand, she thinks it is probably physiological.
Thinking back, mum believes this all started when we had the 48 hours of Harry and then Ron being sick with vomiting several weeks ago. At that stage, Ron had nearly caught up to the other two in size. While Harry quickly shook it off and got back to the business of growing, we don't think Ron has been 'right' since. He is now about two thirds of the size of his siblings. We've been trying to get some weight on him for a long time, but he is still very thin. We make sure he is getting fair access to the food, and he eats like a champion, so something seems to be happening after the food gets in his body. Hopefully we'll get a better understanding of what is happening soon. The Weasley twins are continuing to grow every second. Their eyes are nearly completely open now. We also have a surprise- turns out that George is actually a Georgie!
