Welcome Citygirl,
The mother usually feeds her babies once a day and that's generally atdawn (5:00 a.m. or so). Keep the babies in the nestbox or she won'tfeed them. If in the morning, the babies aren't round and look likethey swallowed a golf ball with warm bellies, you can try to put themon the mother's nipple. They don't take long to nurse. Afterwards, youmight take a wet cottonball and gently stroke from their bellies ondown to their tail so that it stimulates them going to the bathroom.Does usually lick their babies that way to make them go to thebathroom.
If you can't get them to take to the mother's nipple, you can syringefeed them with goats milk or KMR (kitten milk replacer) with a touch ofcream in it if you have it about.
You'll need a syringe and don't give them much more than 2 ml. perfeeding until they're a week old. Feed slowly so that they don't getliquid in their or drown since they're so little.
I'd get rid of the soiled hay in the nestbox.
Keep us posted.

P.S. Does usually don't sit on the nest with their babies because inthe wild, that would give away to predators where the nest is. She maybe sitting off to the side on purpose. As long as they're in thenestbox and remain there, hopefully she'll care for them. If this isher first litter, she may be somewhat confused as to what's going on.
