Congratulations on your litter and sorry for your loss, I really did not know how many people breed girls under 5 pounds.. My son kept telling me how risky it would be for my Prada and she was 5.5 pounds so I had her spayed,at 6 months thinking she was going to stay that weight... she is now a wooping 6.5 pounds, which for me is not that much more...LOL Now I am breeding my silky girl she weights 8.9 pounds and I am still nervous..
best of luck with mom and babies... post pictures in the nursery when you can so we can meet your babies..
hugs,
