Also as our dogs are family members they sometimes fee torn between their responsibilites and beign with us.
I personally encourage the bitch to stay with her pups all the time only allowing her out to the toilet at frequent intervals for the first two weeks. I spend some time in the same room reading quietly etc, but the mother pup bond is first.
The first three days you practically find they never leave the whelpign box, this ensures the milk comes in properly (as with us the true milk arrives in volume about the third day). After this she is likely to spoend time out fot he box as it will be too warm for her.
Another reason for restless bitches is pups getting overheated and restless, but you don't mention this.
If she is wild eyed panting a lot as well as restless then a Vet visit to rule out Eclampsia would be a good idea.
