Some practical things that work for us:
Get a cleaning/ironing person so you don't spend the wekend doing chores
Get an internet shop delivered weekly, at least for the boring basics, you can then potter at leisure round the supermarket instead of having to do a mega shop on your day off
Get everything ready for work and nursery the night before: e.g. clothes, bags packed, packed lunch
Have emergency cash in bag at all times for for mad taxi sprint incase of problems with public transport, student demos etc
Get friendly with other local Mums and help each other out with childcare
My friend tell me that nannys and childminders are more willing to have a child who is feeling a bit under the weather and are more flexible with hours than a nursery (we went with a nursery though)
Read up on the law around family friendly working and yours/your husband's company's policies on time off for emergencies, parental leave, homeworking etc, all of which you could use if needed.
Be prepared to use annual leave for childcare and not for holidays!
Make sure you and your husband share responsibilities equally. I am an HR manager and see far too many women taking time off for their chidren when their partners do nothing "but his company wouldn't let him have a day off" - erm they have to, it's the law!
If it's not working for you as a family after a few months then do something about it - another job, different childcare, different work hours might all improve the situation.
