Dottie is on her 4th month of not eating but then again, she is just over 3.5 years old.

I would try every week or two. Also double check everything like temp, humidity, security etc is good. If it's a baby, my bet would be on a husbandry issue. Dottie was labeled a 'problem feeder' and they had to assist feed her as she didnt eat for almost a month. I got her home and set up with the right temps and hides etc and in 2 days, she was standing up like a cobra gobbling down anything that got near her. She ate every 3 days until 6 months old like clockwork.
