Well done on breeding them! Doesn't happen too much unintentionally.
Anything will eat these frogs eggs...so best to leave them to it. Also I would give the poor female a break tbh. Usually its best to have a couple of females to one male to ease the stress off of one female. Producing eggs much less laying them takes a huge toll on the body whatever animal, she will need a break from constant breeding. Male frogs in particular of any species absolutely pester females and can cause the female a lot of stress.
Feeding wise crushed up fish flakes will be fine. Daphnia and brine shrimp as even if the taddies can't swallow them whole they will all 'chew' on them together. As they grow larger a good pelleted food would be good. Again you will find all the taddies sorrounding the pellets and 'chewing' them. Hope this helps. Be careful to avoid over feeding though, tadpoles really don't take in much food!
Also, you will probably find that leaving the taddies in the tank will get eaten by the parents. What are you feeding mum and dad? Mum will need some good nutritious food at this time so bloodworm, daphnia and brine shrimp will be great for her. I also gave the odd pinhead cricket which really boosts nutrition intake for them
