keep up the good work and keep offering live food items. it's hard to say how often any one gecko should shed. many factors come into play like age, growth rate, food intake, etc.. i find my young fast growing ones shed every couple weeks \- some. don't think you have any probs there, shedding more often could be a sign its growing some and putting on some weight.
