New father makes mental note of the economic upside of breastfeeding, passes those savings on to his beloved wife.

Last October, Japanese Twitter user Daichichi gave birth to her first child, a healthy baby boy. She made the decision to breastfeed instead of using formula, and since then she’s been supplying her bundle of joy with nourishing mother’s milk.

Last Tuesday marked six months since the baby was born, and while it’s not necessarily a Japanese custom to celebrate half-birthdays, Daichichi’s husband felt a celebration of sorts was in order. But it wasn’t the baby who received a gift from Dad, but Daichichi herself, who shared her story in the following tweet.

On their son’s half-birthday, Daichichi’s husband gave her an envelope with a written message which read:

“It’s not much, but this is in appreciation for the past six months. Use it however you’d like, and thank you for all your hard work.”

Inside the envelope? 100,000 yen (US$935), to compensate Daichichi for a half-year of breast milk.

A husband giving his wife a gift of cash might a little strange, but it turns out that several months ago Daichichi mentioned to her husband that she’d heard babies require about 140,000 yen (US$1,300) in formula during their first year, and facetiously asked if she’d be able to collect that much in payment for her services. But while she’d meant it as a silly joke, her husband thought it over in earnest and came to the decision that she really did deserve to treat herself to something nice in recognition of the loving care she provides their son with (and apparently decided to toss in a bonus, since by his wife’s calculations a half-year’s worth of milk is only worth 70,000 yen).

Daichichi’s tweet was met with a chorus of congratulations for having both a happy baby and a wonderful husband. She herself agreed that she’s been blessed, likening the experience to the mixture of satisfied pride and thankfulness she felt when she received her first paycheck from her first job. And lest you think she’s just selfishly basking in the joy of a windfall, she later expresses her regret at not preparing anything to say thank you to her husband for his parenting contributions thus far, but given the obviously strong emotional bond between the two, odds are the new parents will be finding ways to surprise and delight each other for a long time to come.
