a full litter can take quite a while to pop out - my old bitch's first litter took close to 48 hours to emerge
it's important to keep a very watchful eye on mum - looking for the signs that the next one is coming - and make sure that those already out are safely out of the way = i'm sure you know what you are doing - just stay alert
