Hi Mango! Congrats on the baby! What an accomplishment.
New babies are challenging, and amazing too. I hope you don't mind a suggestion from one mother to another. Sometimes, babies freak out. I would very carefully check to make sure she's not in pain in that Snuggli front pack. Make sure she's safe and comfortable. And then, if everything's okay, I would just put in headphones and let her scream at me while I did the treadmill. (assuming the treadmill is at home -- I wouldn't subject strangers to it =)
I, too, had a baby who seemed to cry a lot. I used to try everything to sooth her, and often just ended up sitting down and crying with her myself. Then, I realized that it's not my job to make everything all better for her 100% of the time. Sometimes, it's okay if she cries, as long as she's safe and comfortable.
And then, she'll have a happier mom because you won't be so frustrated in your goals all of the time.
Just a thought.
