I don't normally do the soppy, normally more along the mum blogs about the juggling and chaos and constant drudge, questions and no time alone.
All of the above is true, you will do more domestic cleaning/drudge than you ever thought possible, you will become a short order chef, if you work you will have three jobs (children, actual job and childcare organisation/firefighting) and feel like you are crap at them all.
It is a bit crap really but it is totally outweighed by moments that shine through.
As little babies - any feed that goes nicely, holding them sleeping. Drink it in and don't forget it.
As older babies - those cuddly rolls of fat, the bug gummy smiles, the endless discovery about themselves and the world. The constant companionship you start to discover they bring you at this age.
As toddlers - how proud they are when they achieve something, the way they discover how to show affection towards you. The delight when something is funny and you laugh together. How everything new seems magical.
As pre-schoolers - they start to seem wise suddenly, like they have something to tell and show you. They are funny and the companionship starts to turn into proper company. They will vocalise and draw affection. 'I love you Mummy' are magical words.
Infant school - They are starting to find themselves in their own little world, make friendships, learn, prefer things, chose things, decide things. They are emerging. They still think the best thing ever is a day with you.
Still waiting for junior school and secondary school as eldest is 6.
If you can have lots of them, watching them interact together is the most incredible thing.
The above is more magical than anything you can imagine. It does not make clearing up a plate of pasta and sauce from the floor any less swear inducing however.
