"Which means that she may have had NO time on her own with DP since DC was born, certainly much less time than some posters with family and friends nearby who are available to help with an evening of babysitting etc."
How can you possibly have had NO time alone with your DP?
All children sleep!
I'm serious - my DS1 is nearly 4, DS2 is 14 months. During that time I have had ONE night away (DH stayed with the kids). DH has probably had a total of 2 or 3 weeks, mostly business trips.
We don't have family very close by and both my children are terrible sleepers so I can count the nights out we've had together on the fingers of one hand.
Other than that, zilch. I didn't even get a night away when I gave birth to DS2
But I'm not putting myself up for some kind of hardship award here. This is NORMAL. This is what life with children is LIKE.
We have a wonderful social life - we attend weddings, go on holiday with friends and family, have people over for dinner, go to the pub, and at night, when the children are in bed, we have lovely evenings together just as we did pre-kids.
I'm not saying everyone has to be with their kids 24/7, but to pretend that extended alone time with your husband is some kind of marital essential is just silly. It's not.
