It is important to feed the right size food at every stage of the pet's life. That is why I prefer dubias (and run a website that sells them) because they are softer bodied that the popular pet store option crickets, and they grow slowly so you can buy them in bulk and feed them over time without worrying about them getting too large. They also have a ton of nutritional advantages over crickets, but are cheaper than a lot of the other options out there.
