As Verulam said, first you make an appt and take mom & all the puppies in to your vet (ASAP) for a post-whelp check-up. She needs a clean-out shot to make sure she expelled all after births AND puppies. She needs to be checked as to milk production, and nipple health.
The vet needs to examine the puppies & their sucking reflexes (look for cleft palates & other congenital defects) & can best answer where they should be, but right now (they need to be in a whelping box). They CANNOT regulate their body temperature, so the room with AC may be off-limits.
The mother dog should have gotten USED to sleeping IN the whelping box where she was to RAISE the litter LONG BEFORE NOW!
You or one of your parents need to be on a sleeping bag or air mattress (24/7) beside the whelping box to BE SURE she does not roll on, or SUFFOCATE any of the puppies.... for at least the first 3 days.
The vet can also answer questions about HER DIET. I highly discourage ANY HUMAN food. She DOES NOT NEED IT and it only spoils her appetite for dog food. There is NOTHING balanced or helpful about it.
She should have a powerful appetite (not having - one can indicate a problem) in order to be producing enough MILK and needs to be eating about double her normal amount of kibble, in PUPPY FOOD for the next 2-3 weeks. Again, if your reading did not spell all of this out => ASK YOUR VET or your breeding mentor.
Your puppies will need to start on a liquid worming program at 2 weeks (by weight). They need to be wormed EVERY TWO WEEKS! Vet can send you home with proper product & YOU need to be WEIGHING the puppies ever day or two; to see weight gain (if they are doing as well as they should be) on a human baby scale, or if a toy breed - you might use a smaller (gram) food scale.
Finally do not even consider KEEPING all of the puppies! They will have or develop LITTER MATE Syndrome. (Google it.)
