some great replies so far!
I have just returned to my career after 5 years of being a SAHM I also have 6 DC aged 12,11,8,6,5 and 2. Currently I am working 3 days/week, but have just got the permenant contract for 4 day/week job.
If you havent worked for a while, and are unsure about how to get back (like I was) try contacting past bosses/colleagues that you got on with and asking for advice on ways back in. I emailed an old boss of mine, to ask if we could meet to discuss good ways for me to get back into the profession, and she emailed back almost immediately to say they were desperately looking for someone and when could I start!!
Finding the right childcare, as mentioned, is vital. Initially we went for a combination of nursery for ds2, and after school clubs for older dc...alll turned out a bit of a nightmare, but have now hired a Nanny. Total monthly cost is approx 2X what we were paying, but benefits make it worthwhile. We are seeing it as long term invstment. Once ds2 is at school our childcare costs will be less, and it will therefor seem more worthwhile me working, but for now we are hoping a Nanny will save my sanity!
You do definitely need to think about plans for when DC are ill. This was a major pain for us, as with 6 of them there is often one or other ill, and we have NO family nearby...
Talk lots to DP/DH if you have one. There will be lots that needs to be shared , not just the obvious. EG my DH has accepted he needs to put the dishwasher on more often, or even put a load of washing on once in a while
but I still find the majority of the thinking/planning/organising for dc is down to me, eg attending meetings for dd3 at school(special needs), sorting out any niggles with the nanny, arranging bday presents and parties etc...so all these things need to be shared out....
If funds allow definitely get a cleaner. You dont want to spend days off paid work cleaning!
Be prepared for DC to take time to adjust , and try not to go down the whole guilt route when they make comments like "I wish you could still pick us up from school Mummy...sob..." If they are old enough try explaining to them the benefits of you going to work...
Try to plan nice things to do at weekends/days off paid work, that way it avoids the feeling that the weekends just dissappear and your back to the girnd of Mondays...
Be kind to yourself, let your standards slip
(even more in my case!) Try to let go of your need for perfection (speaking personally again LOL)
Treat yourself to some new work clothes - they will halp you feel confident even if your not!
....may be back with more...and in the meantime I will try and take my own advice as I am having a major wobble this week about going to 4 days LOL
