At 16 I did a nanny stint for the summer holidays and 16 years old is still legal for your three dc to have as chidlcare.
If you take 6 days off through the summer and your dh takes six days off through the sumemr -then you have three days each week to find soemone to care for the three dc - that reduces either a childcare bill or some swapping with other parents - though finding other parents to have three more dc may be an issue.
It isn't easy trying to juggle chidlcare and not having grandparents on either side isn't always going to make any differnce, some point blank refuse to help in anycase.
it is daunting thinking - I have trained for a new carer and oh I can't actually start working as 14 weeks is to long to juggle everything.
Somehow you do and you get by with a variety of higgled pigglety processes.
i still think the easy way is to get an au pair or teen help for the main summer hols and juggle a bit more around the other shorter breaks. It may be the more expensive option but with three dc it may not be as the holdiay clubs would mount up anyway.
Have you got a local college where they do childcare courses?
I have never yet had a prblem and i just don't think about chidlcare - if I am lucky there dad would have them for 4-5 days during the hols - leaving me with 5 weeks to sort out with friends and swapping, and then my own hols which I tend to take nearly three weeks in the summer hols at the end of August so I get through the first three weeks and then can relax a bit [gr
When I say i can't afford to go away in school term time people on here says it is still expensive - it isn't with childcare and steress of it for me
