I can relate NormanTebbit - I'm coming up to six year SAHM and it gets duller and longer I do it for the more options I fear it closes off.
I realise there are no perfect options though would dearly like to do part-time working but with childcare and transport costs hard to make it worth it - though might change in September when second DC starts school. I have no family round to help and DH works long hours and is often away. At moment three times a day I have to be at school for pick-up and drop off's - which limits have far I can get especially as driving to expensive as we only have one wage coming in.
Not having two wages coming in places huge restrictions on what we can and can't do. I am rarely in the house all day with the DC - I do find a lot of cheap things to do - but even this annoys family, friends who work and occasionally DH who does not 'get' this or the fact is I am in the house I'm frequently busy.
The lack of affordable childcare restricts with volunteering as well - which people often cite as something SAHM should do and again makes it hard to afford re-training courses - even the OU which I am finally doing takes money to pay for the courses.
There can be a lot of pressure to enjoy these years - they have gone fast but when you have three under fours and have not slept a full night in years, have not had a afternoon breather with naps since eldest was 18 months and me time a weekends though promised never seems to materialise - it gets hard.
I do not regret these years and will be back at work at some point - then juggling DC and work - but day to day it can be hard. I have a lot of good memories and as DC are getting older it gets a lot easier but no-one in reality is Mary Poppins every day but I at least feel I somehow should be.
It nice to hear it not just 'me'.
Oddly I never expected to enjoy all the time at work - always thought the money and spending power it brought compensated for those times.
