I am no doctor or psychologist but I will have to say
This has alot to do with W just having a child.
I would try not to react or read so much into it.
Give W a chance Help more then you would usually. Bring W her favorite flowers Her favorite dessert Without expectations or expecting something back.
Just because...
Even a Thank you letter hand written...
Trust me a woman feels abandon at a time like this, Your W just had a baby....
Just remember One day at a time
