F.C.
I suggest keeping a schedule and arranging the space you have in order to accommodate the activities you plan to do.
For example, you may want to create a work space that keeps your 2 yr old within vista. (You really should not leave them completely unattended) Then, plan on working in 30 minute shifts and then taking a 10-minute break to play with your baby, snack time, change diapers or doing potty time. You may want to cook early in the morning or the night before and then just heat food during the day.
To keep your baby entertained, set up "centers" where she can explore, so like a library center, a lego center, a doll center, the craft/coloring center, etc. and then switch these centers every few days so she doesn't get bored.
The more organized YOU are, the smoother things will run. It's not easy, but is do-able!
Good luck!
