is it ok to feed the baby goldfish twice a day i have to work full time shift now?????

Have you been feeding them more than twice before? Just wondering, since you mention "babies". If they are truely still small, they need more feedings than an adult, and if you give them just a tad extra when you feed them, so they have to nibble on something for a few extra minutes, then twice a day should be fine....

yes and still living there must be a few 100 in there i have a tank full do you think they'll servive for the rest up there growing up thing im amazed that they live this long period of time now being three weeks??

Wow, a few 100!!
Well, you can put things in that they can nibble in all day without you having to look much after them - plants for one. Anacharis, duckweed are good examples. Or you can try and hatch brine shrimp eggs (instructions on how to are usually on the package, and its fairly simple), and those newly hatched brine shrimp stay alive for a few hours for the goldies to eat....
