My boy Steve is like this; I've only had him since December, but soon after bringing him home he shed his tail, all four legs and his head; he went exactly like your baby has! He's shedding his body now, and it was as white as your picture a few days ago; but I'm starting to see the colour of his new scales break through, and when that happened last time he finished his shed within the next 48 hours.
I was shocked, to say the least! My big girl Ruby has only shed once in the year I've had her, but she was about 2 & a half when I first got her. It was nothing like this! My mother was minding Steve for me while I was away one weekend, and when I came home I thought something had happened Steve and my mom had replaced him with a snow/albino dragon!
Beautiful little girl you got there, by the way. Adorable. You'd think she'd be cranky with that shedding, but she's like "SMILE FOR THE CAMERA". They're all little posers. :roll:
