Same for my family. My brother doesn’t flush the toilet and doesn’t aim well, hands also briefly washed. My dad often clear his nose with his hands and smokes and didn’t wash his hands and touch LO, and my LO has smoke smell. My entire family hygiene is 1/10, but my baby is 4mo now, he has great skin and touchwood haven’t fall sick. Maybe clean your LO as often as you can. I did that and my mom still scolded me for being anal -.-“
