Author's Note: Really, how could you ask a question like this and not request an answer from Timmy's godparents? I'm starting with Wanda because I've found it easier to write from her point of view than Cosmo's. In this segment, you'll find my attempt to explain the disparity between Wanda's personalities in the Oh, Yeah! Cartoons shorts and the main show (look in the fourth paragraph).

I hope you all like this!

Wanda Fairywinkle-Cosma

There's no one particular reason why I love Timmy. That would be like asking me why I love Poof. To which I would say: I just do! Not because he's cute, or because he's always smiling, or because he hardly ever throws a tantrum, unlike some babies (though those qualities are definite bonuses), but because he's my son.

That's how it is with Timmy as well. I don't love him because he's clever, or because he makes me laugh, or because whenever he apologises, he means it. I love him because he's my godson. It's as simple as that.

I don't believe in love at first sight. How can you adore someone you don't even know? You have to interact. You have to find out their likes and dislikes, their hopes and fears, their strengths and weaknesses, before you reach the point where you could possibly fall in love with them. That's the process I went through with Cosmo. My first impression of him was hardly stellar – he ran me over with his car! It wasn't until after I'd kept bumping into him at high school and at the diner that I saw the sweeter side of him and realised how much I wanted to be with him.

I went through a similar process with Timmy. When we were first assigned to him, I tried to be friendly and just a little bit silly, as I am with any kid who needs to relax and be reassured. As time went by, I learned which aspects he responded better to. I could tailor my reactions, my whole personality, to be exactly the kind of parent Timmy required: caring but firm. He was pretty adventurous and needed boundaries, but he also needed the affection and attention that his real parents didn't have the time to give.

I still make mistakes sometimes; there are days when I can read him like a book and days when the situation is as clear as mud. There have been plenty of times when he's called me a nag and ignored my advice and got himself into trouble because of it. But I haven't given up. That's not what you do when you love someone.

It's because we've spent longer with Timmy and come to know him better that we feel more responsible for him than for any other godchild. We want to see him smile. We want to help him learn from his mistakes. We want to keep him safe. Which is easier said than done, because there's a lot we have to keep him safe from.

Take his babysitter. What can I say about her that hasn't already been said? She lies to everyone she meets. She wreaks havoc and blames it on whoever's unlucky enough to be in the wrong place at the wrong time. She lives to spread pain and misery as far and wide as she can. You can't spell "Vicky" without "icky".

And yet, in some strange way, I suppose I should thank that woman. Without her, we would never have met Timmy.

Of course, this love isn't just about what I'm trying to do for him. It's about what he's done for us. He's the one who saved us from Mr Crocker's clutches. He's the one who gave us Poof and brought a bundle of joy into our lives. But it's not all about daring escapes and world-changing wishes. There are plenty of little things which remind us how much he appreciates us. He cleans out the fishbowl without being asked. He surprises us by leaving out plates of chocolate (for me) and red meat (for Cosmo), even when there's no special occasion to celebrate. He does it because he wants to.

He's part of the family.

Almost.

Sometimes I forget he's only human.

One day, Vicky was taunting him with her shiny new mace. (Where does she get these weapons? The Internet, probably.) She was chasing him all over the house, doing everything she could to scare him, and he tripped over his own feet trying to get away and … he fell down the stairs. That image of him at the bottom – tears in his eyes, limbs bent at odd angles, clothes stained by his blood – will haunt me for years. He's been through so much for us, so much because of us, that I almost forget how vulnerable he is.

Until something like that happens.

He quickly wished away all the injuries so Vicky wouldn't get in trouble, so she could still babysit him, so he could keep seeing us. I don't know how I feel about that. It's great that we've been together for so long. It's great that he wants us to stay together for even longer. But does he have to go through so much turmoil to make that happen? Why does Vicky never have to suffer the consequences of her actions?

Maybe it would be better if Timmy let his parents see Vicky's true colours. If he let the cops send her to prison. If he let the misery out of his life. Sure, if he did that, we would have to leave, too, and it would be tough on him. But I think I would rather leave knowing he's safe and happy than stay precisely because he's in pain and crying. It's not nice to see your loved ones be sad.

Besides, I know we'll have to say goodbye sooner or later. No kid needs a babysitter forever. No kid has the same fairy-obsessed teacher forever. No kid can be bullied forever. At least, I hope they can't.

But we've hung around for so long! The thought of wiping his mind of any trace of us, the thought of him forgetting how much he means to us, the thought that all of this doesn't even matter … it just breaks my heart.

When you start training to be a fairy godparent, Jorgen always warns you not to get attached to your godchild. But you do. Of course you do. You can't help it.

And I can tell you now that the day we disappear from Timmy's life will be the worst day in my 768,321 years of experience.
