I wouldn't worry too much...maybe bump the humidity up to around 80% to help, or soak her in warm water for 15-20 mins then let her rub against something (like tree bark) to get the shead off.

My girl turns milky for a day or two, then turns completely normal (without actually sheading) for another day or two before she FINALLY sheds...so I wouldn't worry to much, she'll shed when she's ready!

Hope this helps...at least to put your mind at ease
