I'm not sure if this is the right thread!
Basically my son started a relationship with his
Partner a year ago and now have an 8week old son.
During her pregnacey they had one or two rows but
It's now everyday and I've realised she probably had BPD
Since she was 13 ish . She is 19 now. She is so nasty 
To my son and her mood switches from one extreme to the other
She now sees me as the enemy because I ve said I think she needs help 
Mentally and help with my Grandson as she is becoming
A bit if a worry to myself and son as to how she cares for him.
I have mucked everything up now as she has moved them 
All out so I can't keep an eye on things
