Crickets should be gut loaded with carrots, lettuce, crushed oats/cherios for 24-48 hours before feeding to increase their scant nutritional value. Not dyed Night Crawlers (Walmart and local bait shops) are the best nutrition. But you will need to cut up from pointy end into mouth size pieces for babies and body length for juveniles. Once frog reaches around 3 in. you can feed whole ones without a problem. Good luck !
