Raising awareness about "night-crying"

Today, and April 7th annually, is Night-Crying Improvement Day 夜泣き改善の日 (yonaki kaizen no hi) in Japan. The anniversary was created by a pharmaceutical company that makes over the counter medicines.

The date April 7th comes from the fact that 4/7 can be read as "yonaki, the Japanese for night-crying: "yo (4) naki (7)". In Japanese, "yonaki" is the common term used for babies and infants who cry persistently at night. The purpose of the day is to support babies and parents who struggle with night crying and raise awareness of the issue.

Of course, the pharmaceutical company also takes the opportunity to promote their product; a traditional pediatric remedy that is made from carefully selected natural ingredients, much like "gripe water" in the West.
