When people offered advice before you ignored it. However weaning should be between 3 - 4 weeks but if the mum has plenty of milk and the pups are growing well there is no need to rush it, and once you start supplementing the food and then feeding them she will stop clearing up after them so I like to let them feed as long as the mum will allow but offer them food as well. I start my pups off on human quality raw beef mince. Also something like weetabix soaked in goats milk (cows milk is too rich and will give them the runs).
You can also feed them soaked kibble if that is what mum is on and gradually feed it drier as they get older. Make sure she can get away from them if she wants to, by being able to jump out of the puppy pen or else they will make her sore. Also make sure you are trimming their nails to stop them scratching her. Have you wormed them yet? They need doing at 2, 4 and 8 weeks.
