But you know what? These are all acts of love. I seriously believe that for the babies what comes through is that warm attention and support. The organic unicorn tears are just incidental!
Yes!
Can I also say that understandably sometimes these actions come from a place of grief/fear too.
I lost 3 before dd and she was in scbu for a time herself, I'm sure that's why I was so over-protective, I've noticed that friends and family and clients who'd experienced fertility issues, pregnancy and infant loss were also the ones more likely to be over-cautious. 
Totally understandable to feel on high alert and cautious with preemies.
And yes @PyongyangKipperbang as I originally alluded to, my ocd went into overdrive as soon as I was home with dd, even the hv commented with concern that my home was too tidy!
@OhTheRoses mine still holds my hand when we cross the road if we're out together! I'm 48 
Mind you my brother (46 year old, strapping lump of a police officer who in his spare time apparently has a sodding death wish with his hobbies - scramble racing, bungee jumping etc) still won't go for a jag without mum! 
@meow1989 oh that reminds me of when I was babysitting dds new half brother (exs first with ow) and I was given strict instructions not to let him on sand...we were going to the beach!
he was fine btw if you discount his trying to eat the stuff!
