Is working from home with children a good idea?

There seems to be this superhero image of parents who work from home….they appear to be able to juggle it all, not have to pay for childcare, and still be home with their kids…but to be honest working full time and being home with your kids sounds unrealistic and exhausting.  How is that possible? What’s the cost?  Are your kids really happy that your home with them if your constantly asking them to be quiet or putting them in front of the t.v?  What are your thoughts?
