Just don't give up yet. Charmer took nearly a week after her section to lactate fully, she had a bad time and it was pretty traumatic. However in the end she fed and cared for them beautifully.
Keep the pup feeding from mum, if she will let it. Give her a meal or treat to distract and relax her while feeding. Offer top-ups after the pup has sucked as good strong sucks will help the milk to come in. The other thing you can try if she is a bit upset is Rescue Remedy... I'm sure it helps!
The main thing is to keep calm and quiet and don't let her pick up on your anxiety.
Good luck. x
