arethey I think it really depends exactly how 'childfree time' is defined. Monday-to-Friday, DH is out of the house 6.30-8. The trains are often delayed or he has a late meeting, so then he might not be home until 9-10pm. Every third week,he works overseas and usually leaves after lunch on Sundays and gets back the following Saturday morning, having flow overnight. He tries to give me some child-free time at weekends, but like this week, he sat up with a poorly child Friday night so I could catch up on the sleep I haven't had during the week. Yesterday morning, DS was booked to go to the photographer, so I took him there while DH took dS1 to do the grocery shop. We all met back at home for lunch, then DS1 had a party from 2-5, so I took him there while DH looked after DS2. We got home about 5.30, had dinner, started bathtime, put a child to bed each, then I came downstairs, tidied the kitchen etc. and DH and I sat down at about 9pm. We had some child free time discussing the schools we viewed for DS1, then DS2 woke at 11ish.
After another rubbish night with a sick child, DH and I have attempted to take it turns having baths this morning, but inevitably children have visited each of us during this time, and we can hear them running round, making noise etc. DH is now about to give me some child-free time, which I will use to put laundry away, clean the bathroom and sort toys that are going to the charity shop. Later this afternoon, we will attempt some family time and this evening, DH will get some child-free time while I do bedtime etc.
For us, making sure we each get some child-free time and spend family-time together is a really balancing act. We try really hard, but it's never perfect, and getting 1-3 hours break a week never feels enough. DH could change jobs, but then we couldn't pay our modest mortgage etc.
