And I feel terrible, but I can't do anything - can I?
She's a young (23ish?) new mum who lives with her partner. Baby was born in October. Her family are all in a different town about 1hr away (I think)
And I'm pretty sure I've heard them arguing a few times since they moved in
I'm WFH today and sat in the living room and I can hear her sobbing through the wall

It would be totally inappropriate to knock and ask if she's ok, because then she'll know we can hear them (only when the tv is off though). But I do worry about her and have told DH and DSD(22) that if I hear them arguing and it gets heated I'll be going round and dragging him out by his ear!
It could be PND, or something else (I do hope baby is ok)
WWYD???
