My ornates are eating machines but almost all of my albino babies I have to force feed them. The best way to do this is to take a dusted superworm or earthworm and while holding the frog gently rub the worm along the opening of its mouth. Then as soon as it opens its mouth push half the worm in there. Usually this will make the frog swallow the rest. Cranwellis are a real pain when they are babies but ponce they reach 3 in. they will eat anything.

If you dont want to force feed another trick is to get some minnows and put a few of them in front of him. This worked for some of my frogs.
