I'm going to interject that Pita might not even think of your daughter as high as another littermate. Some dogs don't realize that young babies are human. They make weird noises, move erratically and smell funky. So they seem like some odd creature instead of mini humans.
However, the same training kind of applies and everyone has good points about starting Pita in some kind of NILIF training and some Puppy Kindergarten classes. Nothing teaches a puppy bite inhibition faster than other dogs to wrestle and play with. Also I would totally advise against leaving Pita and your daughter unsupervised together, even if the baby is in something. Dogs can jump, climb and chew as you've sadly found out, especially puppies. All it takes is that 1/2 second for an accident to happen.
I found using the umbilical method easiest for raising a puppy. That just means keeping them on leash with you or right next to you. That makes it easiest to interrupt bad behavior. Pita is still a puppy, so there is good chance that just training will help. Dogs have difficulty learning NOT to do something. Instead it's easier to teach them what you want them to do instead of what not to do.
The best dog training mantra for just about everything is "Interrupt, Redirect & Praise". Basically you stop them from doing the "bad behavior", ask them to do something "good" and then treat and verbally praise the "good".
It will probably be easiest for you if you try and work with Pita while Makaylee is napping, like in a swing so she'll still be "interesting". Get a load of treats and make sure Pita's on leash. Walk close enough that she can see the baby, but not reach her. If she starts paying the baby attention, call Pita over to you and have her sit, then treat her. Try and do this as many times a day as you possibly can. Eventually you'll be able to get closer and closer and she'll realise that that type of behavior isn't allowed. However I would definitely keep her crated or gated if you can't be in the same room, she's just a puppy but could still do a lot of damage unintentionall

Puppies and children need to sometimes be taught how to interact together. As many Disney and Lassie-fied stories are out there, most dogs don't fit that bill and need to be taught to act that way. I hope that it all works out for you.
