Second possible way of looking at it:
My experience (at it might be very limited) is that friends/friend's girlfriends/wives who seek these "confinement periods" appear to be really high maintenance people.
And seem to go on to treat their children like fine bone china from this point onwards.
My best is still my DH' best friend - at one point he phoned us and said "please come over and see our baby."
I think it was 4 - 6 weeks in, I can't recall.
We were like: "Yes but M does not want anyone there as you guys are meant to be bonding."
He was: "Please for gawd sake come over, don't phone, arrive unannounced, she will be angry, but it will be fine....please come over, please."
Us: "Dude if you are scared of your wife, imagine what we are! Catch you when he turns one!"
The point being, it was really drastic, and actually I felt an overriding urge to go over and shake some sense into her.
I did not - and respected what ever it was that she had going on.
Trust me - at some point, and it is not that far in the future, you and that baby are going to be sitting there staring at each other and you will be begging for company, or wondering why you do not seem to have a social life anymore.
Being a mom does not mean life stops - it simply takes a path, but a lot of people carry on and manage to juggle life and a baby, without it appearing like they are "look at me I have just had a baby!"
