We both work ft oth, have 2 children and are very happily married. I commute 4.5 hours a day, dh drops and collects both children. So yes, I do tihnk it's possible. However, dh DOES have a 9-5pm job and did stipulate when he took it that he HAS to leave on time due to childcare. He has been promoted since and there will probably come a point when he needs to work longer hours. I'm hoping we'll have a house and an au pair by then so it won't matter.
How many children do you have?
I can tell you what works for us:
We have a cleaner, so we don't have to do that and we don't have to argue about who does washing etc
We shop online
We talk for 20 mins uninterrupted most lunchtimes and email each other during the day
We go away together when we can and that's LOVELY but I appreciate you can only do this if you have someone to have the children
I do as much as poss online and at work, eg managing the bank accounts, looking for jobs etc
Although my hours are fixed I end up working 40 hours a week and commuting for 20 so I leave at 7am and get back at 6.30pm
Children HAVE to lay their clothes out the night before and make their own packed lunches, ditto dh and I
There was a point last year when we'd both not been in our jobs very long and were both trying to impress our bosses and we were both KNACKERED but it has got easier. I'm a contractor so I can walk away or get fired at any point and dh is expecting to be promoted a lot in the next few years so he can earn more and I can step back a bit. But that's because I want to, having worked my arse off for the past 4 years.
