When you say "just given birth" are we talking minutes, hours, or a day or two? And, not meaning to be rude, but why on earth have you no emergency supplies like nutrodrops or colostrum never mind whelpi?
Edited to add: why are you not gently restraining the bitch in a lying down position and physically keeping her with them until they have suckled?
Sorry to ask more Questions than provide Answers ....
