Mine just started hatching last night! Its exciting/scary for me!
I have been following the advice that people on caudata have been giving me but if somebody else has more advice I will gladly take it as well!
So I was told to keep the eggs in a small tuperware container, with a airstone in it and just leave them be until they hatch, just keeping an eye on temps(Between 17-20C) the lower the temp the slower they will develope so the more time to have to prepare. I left mine at about 62F(Which is just "room temp" for me) and they started hatching day 17(Only two as of now out of 35)
As soon as they start hatching, I am just carefully moving them to another small tuperware container, in which I will leave all 35 in there till they start to grow and I will seperate them by size.
It is just a small tuperware container that I add a small amount of water that way they have a better shot at eating the food you put in it

I have a total of 8 of them ready to plop babies once they start to grow. No airstone + 100% daily water changes after they hatch. You can put an airstone(somebody correct me if I'm wrong!) But It is hard to split a airpump 8+ ways! and regardless you still need to do the water changes so I would just leave it be for a while.
For feeding, I was told to wait for the first baby to hatch, and start my baby brine shrimp, since the babies will be eating their yolk for the first 24-48hours that gives you time to start up some live food for them!
There is an awesome thread here about how to grow and harvest BBS, I'm following it and hopefully my babies will have some BBS soon!(this is the part im the most terrified about!)
Just enough water for them all the swim around is all they need at first, because you want to make sure they are eating all they can fit in their bellies and sometimes they can just lose the food if there is to much "extra space" you know what I mean? so just shallow dishes or tubs is fine! I just went to the dollarstore and bought a few
