I read somewhere that hatchling sulcatas require much higher humidity than one would expect....almost 60% in at least part of their habitat?

Do any of you have any suggestions for how much humidity baby (2 to 3 month old) hatchlings should have?

Is it true that too little humidity will cause respiratory problems?

I recently got a hatchling and have never done the "hatchling thing" before. My other sulcatas were at about a year old or older when I got them.

Thanks for any help.
