I'm not a breeder so you need to take mambas and brainless etc advice on that but I did help out with a litter of a Mum had a C-section, 2 were born mummified and 2 healthy - mum had no milk for 3 days - pups had to be bottle fed and then also put on the teat to try help quieten them between feeds and stimulate mum's milk. Mum was very lethargic for 2 days - pups for 1 - though from the minute mum woke from anaesthetic vet said she was trying to get to the pups and lick them before she could even move her head.
The mum carried on cleaning them and letting them try to feed but she had no milk at all (despite injections from vet to help the milk along - 1 after C-section and one a day and a half later). Pups had to be bottle fed and cried quite a lot in between feeds - they were being fed small amounts every 30-45 mins if I remember right (vet wrote down times and amounts to aim for etc etc I don't remember all that as it was a while ago now) - but I helped with the bottle feeding....- we still returned pups to mum immediately and helped them on the teat to try to stimulate milk etc. On the evening of day 3 Penny (mum) got up while her owner was bottle feeding one pup and me the other - she just walked over and sniffed the pup and suddenly pushed the bottle away and put nearly the whole pups head in her mouth (ever so gently and slowly). We put the pup down and hey presto pup went to teat and started feeding - milk had arrived. And it was clear the milk arrived since for 3 days solid the pups had whined when at the mums teat - quietened at the bottle and swiftly whined/cried again until the next feed - as soon as pup went on the teat that 3rd day though the room just went silent - and sure enough its because mum had milk.
I only say this to reassure you that mum may not have much milk now but its a good sign she has any at all so soon after C-section - it doesn't mean she wont have a change and produce more in a couple of days. I'm sure pups and mum will both show you when she hopefully is able to feed them more.
Listen to the others as I know nothing of breeding other than that one C-section litter I helped with but I only write to say don't panic - take each feed as it comes - 1 at a time - the milk may well arrive in plentiful supply soon. But if you are worried keep on ringing that vet or get them to come and take a look - anything that puts your mind at rest.
Best of luck honey - I know the lack of sleep is going to be a nightmare but hopefully things will start a turn for the better soon. Really hope everything goes well for you. You're in my thoughts xx
