This is one of my favourite poems. Print it out for DH?
^I hope my child looks back on today
And remembers a mother who had time to play.
There will be years and years for cleaning and cooking,
But children grow up when you’re not looking.
Tomorrow I’ll do all the chores you can mention
But today, my baby needs time and attention.
So settle down cobwebs; dust go to sleep,
I’m cuddling my baby, and babies don’t keep.^
I've got a nearly 2 year old and another due imminently. I rush through housework first thing and then we go out and play all day.
My house isn't a show home but it's not messy or dirty. If there are big jobs to be done (like clearing rooms out) I wait until DH is off and we do them together.
You need to set this precedent NOW in my opinion :)
Here's a few more wise words 
My dishes went unwashed today
I didn’t make the bed
I took his hand and followed
Where his eager footsteps led.
Oh yes, we went adventuring
My little child and I
Exploring all the great outdoors
Beneath the sun and sky.
We watched a robin feed her young
We climbed a sunlit hill
Saw cloud-sheep scamper through the sky
We plucked a daffodil.
That my house was so neglected
That I didn’t brush the stairs
In twenty years no one on earth
Will know or even care.
But that I’ve helped my little child
To see and learn and grow
In twenty years the whole wide world
May look and see and know.
^That I didn't mop the floor today
That I didn't sweep the stair
In 20 years time no one will know
or even care
But the time that I've shared with my children today
Will be in their memories forever, to stay^

^Come in, but don't expect to find
All dishes done, all floors ashine.
Observe the crumbs and toys galore.
The smudgy prints upon the door.
The little ones we shelter here
Don't thrive on a spotless atmosphere.
They're more inclined to disarray
And carefree even messy play.
Their needs are great, their patience small.
All day I'm at their beck and call.
It's Mummy come! Mummy see!
Wiggly worms and red scraped knee.
Painted pictures, blocks piled high.
My floors unshined, the days go by.
Some future day they'll flee this nest,
And I at last will have a rest!
Now you tell me which matters more,
A happy child or a polished floor?^
