When I began writing this blog nearly a year ago now, I made a pledge to regularly record what we got up to together.
I would include all the good and bad bits.
I thought that some words alongside the 1000s of photos I have taken of you would be wonderful because you probably won't remember these days.
But I haven't been honouring that pledge lately.
I intend to write more from now on because you are both going through extraordinary periods in your lives.
It is worth recording.
Believe me, it is amazing. We are so proud.
We all laugh so much. And cry a little.
And I want to write more because I think you would like that; I would have liked that.
I wonder when you will begin reading all these words and start appreciating them?
I remember the moment you were born just over two-and-half years ago now as though it were yesterday.
Yes that's a cliché but I can't imagine life before February 2011 and to be honest I don't really want to. You have both brought a purpose and reality back into my life.
I thought I would be a tough guy during your birth; but I wasn't.
My bottom lip quivered just a little.
I was terrified and amazed at what your mum went through. Pregnancy and birth is such a beautiful journey and I hope you will experience what we enjoyed in the years to come.
Looking after you both full-time is the hardest job imaginable.
I find it really tough.
But it is the best job I have ever had, or will ever have.
Sometimes I forget that.
I really wanted to look after you both during these early years, so I did.
Mum had to work hard so we could all eat.
We both want to spend as much time with you as possible before we lose you to school, new friends and independence.
And people tell us to enjoy these days with you because they go by so fast. I'm glad we appreciate that. We love being with you.
Today it's Thursday 12th September 2013 and I dropped you off at nursery earlier which you attend one day a week.
They tell us that you love it there, but we wonder whether you suffer.
And we are fretting over whether to send you to nursery for an extra day a week soon.
Who is really suffering separation anxiety? Us or you?
But to be honest I could do with the extra time these days to get some other things done.
That doesn't mean you're no longer our pride and joy.
In many ways it would mean I would appreciate you more.
I'm sorry if that sounds selfish.
Maybe one day you'll understand and I'll feel less guilty.
Today you're going to the National History Museum in London to see the Sensational Butterflies exhibition, which makes us feel so proud.
You're going on new adventures with new friends which thrills us both.
And recently we went to Surrey Docks Farm where you fed the goats, giggled at the ducks but were wary of the big cows.
Then, just as we were leaving the farm a fire engine turned up on a false alarm and you both got to sit in the cab.
You loved it.
I loved it.
And now you're two-and-a-half years old and so full of energy.
You play together happily but fight just a little. We think you'd be lost without each other; it's lovely.
You seem to be happy.
You both make us really laugh. And you make us cry.
But you are our proudest achievements. No doubts about that.
We are both happy and well.
I'm trying to exercise again before my belly turns completely south.
And mum is using a personal trainer (reluctantly) despite working so hard.
You see, we both want to be fit and healthy to know you both when you're much older.
We've yet to take you on an aeroplane for a holiday abroad. But we all love our holidays in Suffolk and North Wales.
I think Chelsea will win the Premiership title this year now that José Mourinho has returned.
And there's trouble in Syria at the moment which upsets us all.
So I promise to write more often and let you know what's been going on.
But you must understand that sometimes I get so easily distracted.
Sometimes I become overwhelmed with trying to work out Wordpress, Facebook and Twitter which stops me writing.
Do these names mean anything to you?
Do you tweet?
How do you communicate with your friends?
Please be patient with me because it will not be long before I'll be repeatedly asking you how to use modern technology.
I look forward to those days.
We love you both.
