Hi there, i think your schedule is a great idea. I am a working mother also and started my son on a simple routine around 6 weeks. He is now 19 months, and though there has been adjustments to his feeding schedule and how many naps he takes, he still goes to bed around the same time most nights.
I've read others advice on not being on a schedule, and my opinion is that children need routine no matter how young they are, your not going to let them make there schedule when there 1 so why 2 months. Plus, being a working mom can be diffilcult when you don't know what is going to happen from day to day with your child.
I referenced a book called "Babywise" and it really helped me understand scheduling for children.
Best of luck to you :)
