That's what I was going to say. I know you love your dogs a lot (that's obvious ), but it really doesn't sound like this situation is going to work at this rate. By saying, "Baby is alpha. She's just acting this way because other people and dogs aren't acknowledging her as alpha", you're actually enabling her to act aggressive.

You are alpha. Period. The dogs shouldn't fight with each other if there's nothing to fight over. Leadership? You are leader; there's nothing to fight over. Food? You ration out food; there's nothing to fight over. Toys? You give out toys and you take them back; there's nothing to fight over. At this point, I think you need to start reigning in the dogs again. Leave no toys in the open. No treats. No collars. No muzzles. No food, etc. The house will be barren. They are fed in the morning and again at night. They will Down+Stay before receiving their meal.

I would also advise to stop putting them in pack order. They are the subordinates. Don't go "Baby is first for treats, Daisy is second, Tikeya is third, etc." That's just asking the dogs to challenge among themselves. If you must feed treats, give them a command and *then* give treats. It doesn't matter what order they're in because the point is that they have to do something for you. Thereby, they're inferior to you. Plus, if Baby or Daisy are truly getting aggressive, there is no other option than consulting a behaviorist or considering rehoming the dog. When Ivy was developing leash aggression, I contacted a trainer first thing in the morning. I, too, was short on money, but the trainer and I negotiated a payment plan. Please please do it! Behaviorists are trained and experienced to nip aggression in the bud. They will know how to fix this!

ETA: Just thought of something. You're probably heavily pregnant right now, right? How often do you exercise the pups? Pent up energy can easily be redirected into frustration and, thus, aggression. Maybe that's part of the problem, too.
