bouder

to sulk, pout; to frown upon, to be discontented with

“La tétine est, en effet, à risque pour l'allaitement. Certains bébés en sont tellement satisfaits qu'ils en boudent un peu le sein.” — Dummies are indeed risky during breastfeeding. Some babies are so satisfied with them that they go off the breast a little.

Inherited from Middle French bouder, from Old French bouder (“to sulk”, literally “to swell or protrude the lip”), from a root *bod- (“to swell”) (compare Walloon boder (“to swell”)), probably from Proto-Germanic *būd-, *beud-, *buzda-, *bus- (“to swell”), from Proto-Indo-European *beu-, *bu-, *bʰew- (“to blow, swell”). Cognate with Middle Low German buddich (“swollen”), Old Norse budda (“purse, bag”), Old Saxon būdil (“bag, purse”), Old High German būtil (“purse”) (German Beutel), English bud.
