One of the symptoms associated with childhood BPD is separation anxiety. If a child is placed in public care from an early age and has separation anxiety, the situation will become much worse. The caregiver will treat the symptoms, but the problem is never resolved.

It's strange, when we were growing up we didn't see these so-called disorders in kids. We behaved because we respected and possibly feared our parents and other adults. In short, we knew our place in the scheme of things. I would no more have demanded anything from my parents than I would have acted up in school or church.
Now, allot of kids are, to be frank, absoulte little monsters. Prima donnas who parade through the malls as if money was their God-given right and we adults must kow-tow to their moods and needs.
And when they misbehave because they lack attention, what's the modern answer? Psycho-babble and dope. Keep them medicated because that makes them easier to deal with.
