A/N: Finally, a chapter that isn't late. I already introduced Levy and Gajeel's kids in day one, but here's some more of that. This is the fourth time my Fairy Tail fan-children appear in a fandom week, due to the prompt. HAPPY GAJEVY WEEK 2016!

Day 3- Children/Parenthood

Levy, Gajeel, Metalicana, and Mizu were all looking through an old photo album (yes, a lacrima existed in which people could take photos).

"Mizu, you looked weird as a baby." Metalicana pointed out.

"Did not! You did!" Mizu shot back.

"No one looked weird as a baby. Stop arguing you two." Levy said. The nine-year-old twins shut up after that. Over the years, Levy acquired quite a fearsome "angry mother" mode.

"They were quite the handful back then, right Levy?" Gajeel said.

"Were not! Were we, ma?" the twins asked. Levy kinda stared.

"You definitely were. You still are now…" Levy answered. The children frowned.

"We heard that last part, ma!" they complained. Looking at the photos, Gajeel and Levy were flooded of memories. Good and bad…

FLASHBACK

First Day of Parenthood

"'Can't wait to see Mizu and Metalicana grow up." Gajeel said calmly.

"Yeah." Levy agreed. The two new parents looked at their little newborns.

"Hey. Kiddos. Your dad's gonna make sure you're strong dragon slayers so you can beat the crap out of Atlas and Nashi!" Gajeel exclaimed. Atlas and Nashi are Natsu and Lucy's children, one month older than Metalicana and Mizu. At that moment, Levy punched Gajeel.

First Month of Parenthood

"Gajeel, they're crying again. Can you just go and change their diapers? I don't see why you can't!" Levy said.

"I've told you! The stench kills my dragon-slayer nose! I'll die if I change those things!" Gajeel complained.

"Jeez, I'll just go…" Levy sighed, getting up.

First Year of Parenthood

"Levy! Levy! They're walking!" Gajeel shouted. Levy dashed into the living room. But when she walked in, all the saw where to sitting babies.

"Gajeel, how many times do I have to say it, stop pranking me!" Levy yelled.

"I'm not! They actually walked! See, I have a photo of it!" Gajeel said, showing his angry wife the picture. Indeed, the children had walked.

"Metalicana, Mizu, I dare you NOT to walk, you hear?!" Levy yelled. This was the beginning of Levy's "angry mother" mode. The twins immediately got up and started walking a bit.

END OF FLASHBACKS

"We were that hard to deal with?! Aw man, we thought we were better behaved than Nashi and Atlas…" Metalicana pouted. Mizu nodded.

"Nashi? Atlas? Well behaved? They must be lying! You two are ANGELS compared to them!" Levy and Gajeel yelled.

A/N: Welp, day three for ya. I had fun writing this. And NaLu just always sneaks it's way into my stories, doesn't it. Happy day three.
