Not sure why my comment seems to have irked you, Nothing. 
It's a nebulous question really, without knowing what specific situation we're talking about. I'm sure most parents would feed their child over themselves, take a bullet for them etc if such a dramatic situation happened. I didn't read the OP as referring to war zones though.
I wasn't glib. The 'get help' bit could refer to mental health, yes, or more generally just with life with young kids, physical health, kids' SN or behaviour, financially, whatever. Believe me, I know it's not that easy to get MH help. The parent has resources available, although it might not seem like it. Plenty of posts on here from mums terrified of going to their GP etc to get mh help, parenting help, a food bank voucher, because they think the professionals will judge them, involve SS, the kids will be removed etc. Or who don't ask a friend or relative to help. Etc. It's martyrdom. I do understand the fear. What good, ultimately, is a parent who can't cope, is suffering untreated MH, is hungry, miserable, never does anything for themselves? That doesn't make them able to fulfil the kid's needs either. They might actually resent the kid and be struggling to parent. What I'm saying is, it isn't necessarily as simple as a conflict between the kid's and adult's needs, but actually both are linked. It's not a question of one or the other. Just a thought.
