Not enough milk!

[Taffy]

Do you have a mastitis test kit on hand? If not, does your dairy friend? Her udder was so huge before she had the kids you could be dealing with a low grade mastitis that is not manifesting itself in an elevated temperature or hot/sore udder. I would continue to massage the udder. It's good in case of congestion, will help you monitor the heat and texture of the udder and if Petunia enjoys it all the better.

I'm glad you were able to put Snickers on Lilly. She should increase milk production as her body realizes her kid(s) need more milk. That should also leave more for Sputnik.
