To be revolted by husband swearing at 9 week old baby

[Fate32]

I heard my husband swearing at our nine week old baby because she had a bit of reflux, AIBU to be revolted by this?

Massive overreaction OP - absolutely massive.

@IncrediblySadToo I've only scared myself the once as well, not anything bad particularly, I shouted my DS(5)'s name because he was ignoring me about getting in jammies and the poor kid jumped a bloody mile, I've raised my voice at him but never actually shouted at him because I get very loud, pretty sure even the neighbours jumped a mile

What’s he usually like? If he’s normally decent I would just put it down to him being tired.
