@MangaAce1 It's okay, they only hit her on the head once, they hit the guy twice! (To be fair, hitting her on the head is unlikely to endanger the baby.)
@htt The problem is in that particular phrase "the baby" is what native speakers would use. If you want to keep the cuter baby reference, something like "Baby got us scolded the worst we've ever been, huh..." would sound more natural.
@DeOneChester Between chapters 16 & 17 is one occurrence. But they also got an apartment together, so that's probably not the only time.
