It's a lot easier when you have a spouse/partner willing to be the homemaker while you support the family financially. I would have a hard time working from home if I had to take care of my four year old myself, but since my wife is a stay-at-home mom she's able to take care of the kiddo and making sure the house doesn't fall apart (I won't blame any woman for not wanting to fit the gender stereotype, but I feel kids these days are missing out a lot on not having a parent - dad OR mom - that doesn't have to work and can spend time with them beyond what their work schedule allows).

If you aren't in a situation where you have someone home with you or they can't comprehend that WFH doesn't mean you have to work your 40 a week then sometimes you have no choice but to just put the kids in daycare - which stinks because it robs you of a valuable perk of not having to commute when you have a family.
