It's pretty common in the states I think. I see it all around me even with my "crunchy, overachieving"" friends. Now that we have 2 children DH does the shopping, with list in hand, because it's easier. If we all go and it's a short quick trip, I'll leave the kids and DH in the car. On the weekends DH and I do go out on a Fri. or Sat. night but again, after the kids are in bed and then my MIL hangs out for a bit in case they wake up.
My "me time" is when the kids are in bed
And even then it's not "me" time, I barely ever get time ALONE. And if I did, I wouldn't know what to do with myself, I might wake the baby!! LOL!!
After reading some of the posts I agree, this whole "nuclear" family thing hasn't been around for a while. Usually, it really is/was a village that takes care of the children. It's just not possible alone or is very hard to do it alone, someone suffers along the way be it child or parent. I think we should get back to the old ways of raising children where EVERYONE is looking out for the young ones, not just their parents.
