Your pups look AWSOME!!!! That second shot really is incredible.....I too love how you can see the feet!
Try and get some sleep now....mamma will take good care of the babies. Well, don't sleep too good, you need to make sure they don't get stuck behind or underneath her or under any blankets you may have in there. Remember that they don't produce any of their own body heat for the first 3 days. Also, mamma will need to go out to pee frequently and then want right back in with them. Well, you didn't ask for tips, so I'll try to shut up
Again, CONGRATULATIONS and thanks for sharing those awsome pictures!!
