My son is 4.
But he is also very independent and self-reliant.
He likes:
1) Moon Sand
2) Play Doh
3) Playing on the iPad
4) educational videos
5) playing with his cars and Dinosaurs etc.
6) coloring
7) playing in the sprinklers
8) playing with me.
Working at home with a young child, you WILL have to play with them...and toggle between work and them. In spurts.
So, an idea is:
Tell her ahead of time "Sweetheart, Mommy has to work for about 1/2 hour. Then we will do something."
Then, put out some things she can do. Tell her she can play with that. While Mommy works.
Kids need a head's up about what is going on and what is coming up.
So that they know, it is not endless.
Work in spurts.
If you think that you will be working hours on end... any child will get bored/restless/be not to keen on that.
So you will need to work, then do something with her, go back to work, then do something with her, then go back to work, then do something with her etc.
That is what I do. I work at home too. Not in a major way, but its my own "hobby" type work.
But, my son is good about it. Because, we have a ROUTINE about it.
He goes to Preschool too, part-time. But when he is home, he knows we have this routine. He knows "Mommy works at home.... " type thing.
I explain to him.
He always has things to do. And I also go back and forth between that and spending time with him. And taking him OUT too, for a designated time period. We also have lunch together. We chat and eat and he likes that.
I also give him his own "work" to do. Kid type stuff. Paper, pen, a workbook etc.
Your time of working, will need to be in chunks. Not it being continuous.
Because, we have a 4 year old child at home, too.
So, I know that in my head. My "work" will not be continuous. And will be prone to interruption. It can't be helped.
Balance.
Have a routine.
Tell your child about the day and what is going on.
Have things for her to do.
Let her know what you are doing, and for how long.
Organize your day, as such.
Then what you will do with her.
That is what I do.
It works for me and my son.
My son, also naps everyday as well, in the afternoons, for about 2 hours.
If your work is continuous and you can't get away... then get a Helper, to come and help mind your daughter. And extra pair of hands and another person, will help.
