Hi
Looking for perspective here...
I (marketing freelancer) have been really busy recently. A new contract (days in a client's offices) means I often have to work in the evening on urgent work for other clients.
DH is great and we share childcare drops & the load at home. However, even in busy times we both generally share the childcare collection, doing dinner & bedtime (2 DC under 7) and then I crack open the laptop and start my 2nd session at 20.30. 
DH has a busy employed job and sometimes works of an evening but it isn't everynight as I have this week (until midnight) for eg.
Then in the hols I often have the kids for quite a bit to limit their time in childcare but again I then need to try to do some work of an evening.
My business coach suggested I hand the DC over to DH when he gets home (in the hols as above) to start my work, so I am not working too late.
It makes sense but I am struggling with the idea. I think I feel guilty that I am not gagging to spend the time with the kids, I know they will say "Why isn't Mummy doing bedtime?" and guilty that DH will have to do it all on his own (one DC is a bit of a handful).
Yet on the otherhand I am (selfishly) feeling resentful that I am the one 'losing out' - with no downtime - whilst DCs have a nice week off and DH just carries on as normal. A small voice inside of me is saying ' What about me?'...
Just wondered how others handle this? Or any thoughts?
