Hi Nancy, I just wanted to mention that as they get older, it takes them longer to shed. I've noticed that during the heating season, it takes them longer. As adults, some areas take almost a month to shed. Frequent baths as you're doing is a good idea, you could also use 100% Aloe Vera gel and apply to those areas if you want, just make sure you don't put him under his basking lights after just applying the gel as it could cause burns. You might want to apply it before bed instead so it can penetrate all night.
Kookie looks great, can't believe he's gotten that big already. He looks nice & healthy. 8)
