Trying to run a business with a toddler in the house is a problem of attention rather than of hours. Landra Lynn Jacobs writes the guide for exactly that, and the pitfalls she names are ordinary ones: losing the thread every time somebody needs you, and never deciding in advance which part of the day belongs to the work.
The product reviews make up the other half and they have genuinely been used. A hard floor cleaner gets judged on its two tanks and on whether it really handles wet and dry, with the title asking the rude question outright. A cutting machine gets weighed for whether a hobbyist will keep using it or shelve it by spring. A fragrance gets described by what it does in a room rather than by its notes.
She writes for one specific person: a mother at home who has decided the situation ought to produce something and wants to know which purchases earn their place.
Parts of the work at home framing oversell what is likely. Take the reviews and the pitfalls guide, which are written from experience.
