Baby care is nearly identical to adults. The only things I do different is go with a smaller enclosure (it's easier for them to wander across food dishes at night when they are on the prowl) and mist more often as they tend to be less likely to use water dishes for drinking.
I'm moving my geckos to naturalistic planted vivs with misting systems SPECIFICALLY because the babies seem to do the best in such setups. Make it seem natural with plants and vines and climbing areas, give 'em CGD every two days, mist them daily or 2x a day, and you're pretty much good to go.
I don't start feeding crickets until they grow up a bit, simply because small cricket sizes are a pain for me to get. I only feed crix these days to females anyways just to help them put on a size and weight to get them to breeding size a little earlier.
One thing you will ask with babies is "are they eating?" because they eat so little with tiny stomachs. The best way to answer this question yourself is to look for poop.
hope that helps!
