Advice?

Tessa
I understand it's annoying when someone tells you what to do with your kid(s), but there's certain times where I feel a child's safety trumps this. 
I understand getting annoyed when it's all the time from one person and over stuff that advice isn't needed. Ex; what to do with your child's hair, not to bathe your child in the sink, etc. 
But when it comes to your child's safety, why do you take it offensively? 
By your child's safety, I mean car seat safety, crib safety, etc. 
I'm truly asking. This is something I haven't truly understood, hence why I'm asking for your  explanation(s)
