Do you have any Nutridrops in you whelping kit....available from hyperdrug or any vet chemist ...or some vets. I also had puppy saver from fit and fertile.
I hand reared my last litter due to mum's illness and milk stopping . I used a boots newborn bottle and teat with Lactol once I got the hang of it and into a routine I enjoyed it.
You will find if you make up the milk in the morning for most of the day and use it re heat the baby bottle in a bowl of hot water it makes life easier, test it for body temp on the inside of your arm .
Toilet the puppies before and after feeding remembering to wind the puppies after the bottle feed by gently rubbing thier backs or placing them on your shoulder and pat the back until they burb, I fed the puppies infront of mum outside the whelp box then passed them to her for a suckle on the teat , this kept mum satisfied that puppies were safe as she watched everthing I did then she took care of her babies afterwards as it very important for mum to wash and take care of her babies.
try putting a cushion on your knee hold the puppy in the palm of your hand with the head between your fingers letting the front paws pad into the air (same motion as if padding on mums belly to expell the milk) and the back legs pushing against the cushion on your knee ,rub the bottle teat on the lips of the puppy and he should open his mouth then put the bottle in making sure the milk is in the teat with no air it will take a time for them to get used to the teat and they may want to push it out but persevere (gently) when they eventually get the taste of the milk they will be off drinking in no time.Sometime you need to pup a clean finger in to get them to open thier mouth then slide the bottle in.Some puppies take to it quicker than others.
Also you must use a steriliser with milton for the bottles and keep everything clean.
I bought a travel sterilising kit from tesco quite cheaply, did the job.
I also had fading puppy syndrome suggested to me but my puppies survived so dont give up quite yet.
good luck
