You have gotten some good advice but I wanted to add, I recommend to cut the tv out. I think that overstimulates them in a bad way and interferes with sleeping. Even if it gives you peace and quiet at the time, the long term cost of it is not worth it in my opinion.
Set up your days with a loose structure to them (for example, breakfast, play outside, morning rest, read a book, lunch, inside play, afternoon snack...) And I don't mean you have to play with her, just let her figure out what to do and she can be near you while you are working on whatever you need to do. The routine helps you and them in so many ways.
It is a busy and tiring time of life.
