Septimia
I do think this current fashion of the "isolation" of parents and baby is a bit OTT. It didn't happen in the past but they usually managed to bond OK. My DS went into SCBU and I couldn't get down to see him on my own so waited for my parents and DH to visit a few hours later and accompany me - so my parents saw him pretty soon after his birth. In-laws (further away) were invited to visit ASAP.
But, to be fair, everyone is different and entitled to do things their way. What the new parents don't take into account is the excitement of the grandparents. Perhaps the answer is to let the grandparents have an early brief visit and plenty of photos before parents and baby have a quiet 2 or 3 weeks on their own.
And, of course, while some grandparents can be interfering, many have experience that is useful (as long as they wait until they're asked for advice...)
I think perhaps it’s that the new parents rightly realize is that the grandparents “excitement “ is theirs to manage. Let this be a first and early lesson for thre grandparents that they are extended family now
