Pregnancy is all about restraint — no physical exertion, no Pinot, no putting more than six pickles in your Cherry Garcia.

But you needn’t hold back with Mamatini, an herbal drink for nursing women and expectant moms of at least 36 weeks. Developed by a pediatrician, the ginger/mint-flavored concoction is said to increase milk supply, boost energy, and absorb nutrients that get (literally) sucked out during breastfeeding.

Its formula is secret, but colic-reducing fennel; sleep-promoting chamomile; and vitamins A, B, C, and D promote well-being.

And help your cups runneth over.

Available at Yummy Mummy, 1201 Lexington Avenue, between 81st and 82nd Streets (212-879-8669 or yummymummystore.com); online at drinkmamatini.
