Oh J3mma just thought of this, when my friends have had babies (often very long awaited ones- one friend tried for 15 years!) I usually gave them two bits of advice. I think this advice goes for all kids, especially young ones.
Firstly sleep when the baby/child sleeps, young kids also sleep a fair bit and the advice would be the same!
And secondly, I sent all new parent friends this poem, I love it, and it also applies for young kids.
Song for a Fifth Child by Ruth Hulburt Hamilton (1921- )
Mother, oh mother, come shake out your cloth!
Empty the dustpan, poison the moth,
Hang out the washing and butter the bread,
Sew on a button and make up a bed.
Where is the mother whose house is so shocking?
She's up in the nursery, blissfully rocking!
Oh, I've grown as shiftless as Little Boy Blue
(Lullaby, rockaby, lullaby, loo).
Dishes are waiting and bills are past due
(Pat-a-cake, darling, and peek, peekaboo).
The shopping's not done and there's nothing for stew
And out in the yard there's a hullabaloo
But I'm playing Kanga and this is my Roo.
Look! Aren't her eyes the most wonderful hue?
(Lullaby, rockaby, lullaby loo.)
Oh, cleaning and scrubbing will wait till tomorrow,
But children grow up, as I've learned to my sorrow.
So quiet down, cobwebs. Dust, go to sleep.
I'm rocking my baby. Babies don't keep.
