frustrating ideas from older generations

It's so frustrating hearing the in -laws suggest that my 12 week old baby needs a pillow, blankets, lotion,

a bath everyday, or shouldn't go to sleep too early bc she'll wake up early! f'ing uniformed idiots! pisses me off. What is something others say that angers you?

we tell them the facts and science, but they don't get it. My poor husband slept through the night as a young baby, according to them (1988) he must've been so hungry. They gave orange juice to him at 2 months! Even his aunt said how she told doctor she have her newborn chamomile tea (2000) doc was alarmed and warned her not too, but she still did!
