WOOOOOOOOHOOOOOOOO! A new baby! How exciting. Has mom stopped nesting? One of my girls panted so much and I worried my vet to death having her checked. After her first litter, I wasn't so concerned cause she did it again and then again. She was fine each litter. My vet recommends a check and frequently a shot of Oxy if I was not absolutely certain that every last bit of placenta and cord were delivered. Let us know how she and her "only child" is doing.
Congrats!
