you WANT the deer to get used to the blind but you have to make sure you and your son are,
quiet, not moving or squirming about and make sure you both use a good scent killer each time you head into the blind...
deer detect movement even thru a blind window don't underestimate a deers ability to see you, hear you or smell you
even though you're in a blind.
good luck to you.
