Hi, this is my Diary. Nice to met you, all. I hope you all will have fun reading this.
So, how to call it? “Diary of four sisters”, maybe? But, Limestone, Maud and Marble won't write it with me, so it don't fit.

“Pinkie Pie Diary” is too simple... hmm... “Mane Six Diary”? No, I may ask them to write something nice for you, but is not about them.

You may be wondering why I start a diary at my age. It's teenage thing, right?

True, but this is for you, my son. You are so cute! You will see later your baby pictures.

I officially adopt you today!

I know, I call it ”Mommy Pinkie Pie Diary". I will show it later to Twilight so she spell check this for me, so it will be perfect. But, you can't read yet, so you may try eat a paper. I will give it to you later when you grow up.

So, you probably want to know when and why I adopt a baby, since I'm single.

Believe or not, it all start after Canterlot wedding.

So, my dear Licorice Candy Pie, I meet you when you were left alone.

At first, I was just scared since you have broken wing, and I’m no doctor. You could not talk. I only heard your silent crying in dark alley, so go check it out.

My friends don’t believe me when I say I heard you. AppleJack say to me that, no pony would be on a street with a baby right now, after such a big fight. That's why I go looking for you by myself.

I often do crazy stuff, so they just let me do whatever I want half the time.

After a big battle, ponies celebrate victory. Nopony else heard you. I think we were meant to find each other.

You were really little, in a size of dragon egg, like Spike's. A bit smaller then normal newborn pony. And when I look at your deep, blue eyes, I know I have to save you.

And yes, now I know that when weakest link is abandoned, it woo creatures from other species to take care of it. But, I don't think it was just your magic.

You awoke my maternal instinct, even if, back then I don't dream to take you with me.

I won't lie, to you, in pony standards you are not exactly cutest baby in Equestria. But for me, you are the most sweet baby I know.

In your eyes were tears, I did not know what to do. I never saw a baby like that before.

You may say that baby is a baby, but your wing were so much more delicate then others, your hooves were so little, and so fragile.

You were as scared as me, your little body was shaking from cold. Maybe you were afraid that I will hurt you, since who knows what happened to your real mother?

I try to find her someday, I promise.

Maybe I should take you to Celestia, Luna or at least Twilight, but I decide to keep you a secret.

I was worried that something bad will happened to you if I give you to somepony else.
You know how I love to make all ponies smile, right? So imagine when I saw your sad face.

I tried to hush you, but you won't listen to me. I make funny faces, but you were still sad.
I know, I should not touch you because contact with you is very dangerous, but it was not important to me.

You could easily kill me, since you were newborn with no limitation of your own powers. I know that, but I forgot about it all, back then. I only want to make you feel better.

But, I took you in my hooves and hug you for a very first time. It wasn't smart move. I felt dizzy, and almost drop you, but then I felt this warm feeling inside. I hug you even stronger to feed you with all I got, and I already know that you are not monster.

Ah, my bad, did I forget to mention that? For all of you who reading that, and are not my son (BTW. How you get my diary, huh? Weird.) He is not a pony. My son is in fact a changeling.

Author's Notes:

So How it is so far? Are you like it? I think that Pinkie would do something crazy like that, since she is both caring and happy to help.
