Baby guppies food nutrition diet?

Snacks for baby guppies?
When will they get their color?
How many times will my mother guppy have babies?( she already had 14 and is pregnant again)
Water changes/filter changes?
Additional info?

thanks;)

Suggestion:

There is a food called first bites that is great for fry, or you can put some flakes in a plastic bag, crush them till they're powder and dip a toothpick in them to feed the babies.
It takes about a month for them to get color.
Guppies can have hundreds of babies, they are very prolific breeders.
Just keep the tank clean with regular filtration, if the babies aren't in a nursery basket get a sponge filter so they wont be sucked up.
The mother will eat them if she can,keep the fry away from other fish until they are bigger than the fishes mouths.
