Most of all make it fun! It helps when they are seeing animals and not too cold. Im taking my 4 year old whitetail hunting with me to Michigan, going to sit some ground blinds and taking an ipad with movies and headphones for the down time... trouble i might have is keeping him warm..kids camo is not cheap! Might also take a heater so since im archery hunting ill have to play the wind right.. he has his hunting whisper down. He is crazy excited to go so i hope he keeps it up.
