It’s virtually impossible to treat two individuals ‘exactly the same’ as much as we would like to believe this.
Everyone holds a level of subconscious bias, whether this is a parent finding one child easier to manage due to personality etc and so responding to them slightly differently etc
As I mentioned in my post, children as individuals will also respond to the same stimuli or situation differently depending on resilience etc
Your mother working 3 jobs may have made her somewhat absent from yours and your siblings day to day life for example, you may have coped with this and understood your mum’s need to work and it may have fostered a great work ethic etc in you particularly if you have a good relationship with her, whilst a sibling may have felt slightly neglected by the absence, saw it as an opportunity to go out more, get into more trouble, resolve to be a SAHM themselves or chronically unemployed feeling that they didn’t benefit from your mum’s efforts in the way they felt the should have etc so chose a different path-again same parenting different outcome
As parents we need to be more attuned to our children as individuals, and adapt accordingly eg same situation described above for me as a working parent of 2 kids. When I get home, child 1, seems ok, I prompt conversation re their day, try to engage them in doing something together etc, he seems less interested possibly due to his teenage age, 2nd child is proximity seeking and wants a 20min catch up of my undivided time where we both talk about our days etc have a cuddle etc till he wander’s off somewhere
As a parent, my job is not to think ahhh well I offered same to both boys and only one took up the offer, but to find another way to connect with child 1, understanding that he often wants to chat just before he goes to sleep, will mention something in passing that I have to pick up on or create other opportunities for connection, working that bit harder as they are both different.
We all speak about different love languages etc, I just feel that when a child commits a serious crime a need was not met, this could even be discipline, emotional support etc bearing in mind that adolescents will take risks etc, but we were all teens at some point so why will 1 become a criminal and 1 not?
