I salute you kind sir. We have three sons ourselves (6, 4, 2) and we are strongly contemplating the next :-) Your post is highly motivating and encouraging.
Special kudos for explaining your kids what NAP is. Sadly they don't teach that in schools, despite being the basic moral maxim that every decent person (and institution) should adhere to.
Happy new year from Europe.
Hey congrats on the growing family, and thanks for the comment. Sorry I didn't see it sooner.
