Hey,
Congrats!!! Yep, sounds like you did everything right. My babies usually shed in 3-4 days after emerging from the egg. Then that'll be when they eat. Once in a while I'll actually have a hatchling that'll feed even before its first shed. Not too often but sometimes. You might want to lighty mist the inside of the shelter with water, this way it'll add some humidity that'll help the geckos first shedding. Just make sure you dont get it too wet, or it'll really start to condensate on the inside of the shoe box. Hope this helped...
Good Luck with the little one,
Rich
