Does your shelf liner have some texture to it? You can add a piece of slated ceramic tile in there for her to walk on to keep her nails down --- the PowerSun is a good MVB -- distance w/ a screen should be 14-16 inches -- do you have a probe digital thermometer? If not please get one and get a temp on the hammock -- it will give you actual basking temps and they should be 105-110 for a baby-- w/ the distance of the MVB you might want to add another long tube fixture even a 18" Reptisun T 8 would be good for her -- sometimes w/ trying to get the distance correct for basking temps the UVB ends up being not enough -- but first get the actual temp on that hammock -- and then we can go from there w/ the extra UVB
