I homeschool and am used to schooling one child but now I started 2 kids in school this year and I'm not sure if I'll be able to juggle it well.
That would be hard, can one work independently? 
For some things they both can work independently so I'm trying to pair those subjects up and then do some subjects together with both of them.  I hope I'm doing well enough!
I'm sure you are doing an amazing job, you seem to care which makes you a great parent.
