I was wondering whether English has a phrase or an idiom for someone acting like a baby when subjected to criticism, as well as honest and negative assessment of their actions or personality. By "acting like a baby", I mean a conglomerate of being all offended, resentful, keeping interaction/answers to a minimum by, say, giving merely a "yes" or "no" when you'd normally engage with the person more, refusing to do things they normally would, and all-around passive-aggressive behavior towards those that criticized them.
It's hard to describe what I mean exactly, and if I were to translate directly from my language, it'd be "act like an offended/hurt bride". The word "sourpuss" perhaps comes close, but I don't think it truly captures the meaning. Something that also comes very close is the stereotypical behavior of teenage girls when grounded and then not wanting to talk to their parents, come out of their rooms etc. But this again is just something that comes close, but isn't exactly what I mean. Basically, just acting all offended when one shouldn't be, but should instead accept criticism like a grown-up. Which brings us back full circle to acting like a baby.
