Leopard gecko feeding?

  I dont know how old my leopard gecko is but i had him for 3 months now and he is around 7-8 inches weighing around 40-50 grams. I feed him 2 large crickets every other day that is fine right?
2 crickets aint no where near enough nor is eveyr other day. He is atleast 6 months old at that length and should be easily 50 grams. You should be feeding him every night till he's atleast a year old so he can grow properly. for a gecko his size he should be eating anywheres form 5-7 crickets a night or 15 or so every other night. Yes its alot but at that length hes kinda skinny. Mine at 8 inchs are 60-70 grams (afew at 50s) eating every night atleast that many crickets or eating 12-15 mealworms. No not every night some nights they wont eat but in general most of them do eat alot. My 9 inch one is eating once a week about 12 crickets then with a odd super worm during the week hes almost 90 grams and my 10 inch is eating twice a week on super worms and hes 83 grams.
