There is no handbook for patenting as such
You haven't patented it as of yet?
might be a money maker ;<)
It is so rewarding, but there are tough days too of course.
This.
I have almost 10 years of uncle-ing and ( decades of ) kid sitting experience. In fact, I am kid sitting my 7 year old niece and almost 10 years old nephew. as we speak ( while my twin sister and her boyfriend are away on a 2 week holiday ). I have basically been a father figure since their birth as their dad was often absent. I am actually paid, this time, because 2 weeks is quite the responsibility.
