KNOCK! KNOCK! KNOCK!

"PARTY!" Erin cheered excitedly as she jumped up from her seat and ran to open the door.

"Walk, baby!" Mommy and Mama called after her simultaneously, grinning at each other when they were completely ignored in favor of getting to the door as quickly as possible.

"You're not a party." Erin stated when she threw the door open and saw her Daddy standing there with his arms full of bags. All of the adults laughed.

"Sorry, sweetheart, I just needed someone to come open the door for me."

"Thanks for going to the store, Hank. Just drop those wherever." Olivia said, walking over to take some of the bags out of the man's arms.

"Isn't it time for my party yet?" Erin pouted.

"Almost, lovey. People should start showing up in about thirty minutes." Alex told her.

Sure enough, about thirty minutes later there was another knock on the door. Again, Erin ran to open it and squealed in delight when she saw that Auntie Amanda and Cousin Kat had arrived.

"Hello, birthday girl!" Amanda smiled, hugging her niece.

"Hi, Auntie! Hi, Kat!" Erin beamed, returning the affection.

"We brought presents!" Kat smiled happily, holding two boxes wrapped in brightly colored paper.

"And if you tell her what they are before she opens them, you're going to find yourself with a sore bottom." Amanda warned.

"Yes, Momma. I won't tell." Kat promised.

Erin and Kat disappeared into Erin's bedroom to play while Amanda joined the adults and pitched in with preparations for the party. The rest of Erin's friends were going to meet them at the park when it was time for the party.

"So how much sleep did you guys get last night?" Amanda grinned, noting that Olivia, Alex, and Hank all looked tired.

"Between the three of us, I'd say maybe two hours apiece." Hank said.

"I still think one of you gave her sugar before bedtime." Olivia glared playfully.

"Momma, I'm wet." Kat suddenly walked into the kitchen.

"Good girl for telling me." Amanda praised as she picked Kat up and carried her into the bathroom to change her diaper.

When it was time to leave for the park, it was soon discovered that not everything was going to fit into one car since Erin and Kat wanted to ride together so they could keep talking, so Amanda offered to pack a few things in her own car and take the girls with her. Amanda loaded Erin and Kat into her car and they all drove off toward the park. Amanda deliberately stalled, but the two little ones didn't seem to notice as they chattered and giggled in the back seat. When they arrived at the park, Erin's eyes lit up at all the pink, yellow, and purple balloons and streamers dancing in the slight wind. Erin and Kat immediately ran toward the playground equipment while Olivia, Alex, Hank, and Amanda set out the food, drinks, Erin's birthday cake, and Erin's presents on picnic tables draped with table cloths. Before long, Erin heard people calling her name and her face lit up when she saw her friends Nadia, Kimmy, and Diana running toward her. Erin introduced her three friends to her cousin and all the little ones went back to playing.

"Amanda, will you round up the kids, please?" Alex asked.

"By myself? Time to eat!" Amanda called out.

The hot dogs, chips, and punch were a big hit. After lunch, it was time to open presents. Erin opened each card and read it before ripping into the present in front of her. She was delighted to receive several new storybooks, some new clothes (some for 'little' Erin and some for 'Big girl' Erin), several new coloring books and some new crayons. Everyone sang happy birthday and Erin blew out the candles on the cake, and then Erin giggled as she found herself across Mommy's lap for a birthday spanking.

"One… two… three… four… five… six..." Mommy spanked her so gently that it didn't hurt at all. After counting out thirty five spanks, Mommy let her up and hugged her.

"Happy birthday, baby." Olivia smiled lovingly.

Slices of chocolate cake and vanilla ice cream were passed around. After everyone had eaten, it was time to play a game.

"Daddy, Mama, and I hid Easter eggs all around the park. Each of you gets a basket and you have to find all the eggs. We didn't put any eggs in the trees, so no climbing trees." Olivia explained while Hank passed out a basket to each little one.

"Ready… set… go!" Alex called out.

All the little ones took off in different directions around the park. Some of the eggs were easy to spot, but others were more difficult. All was going well until suddenly Erin pushed Kat down to the ground and Kat burst into tears. Olivia and Amanda hurried toward them.

"She stole my egg!" Kat wailed as Amanda helped her to her feet.

"I did not, I saw it first!" Erin insisted.

"Erin Michelle, tell me the truth. Did you take her egg?" Mommy asked sternly.

"Well… maybe she saw it first." Erin admitted hesitantly.

"I see. Regardless of whose egg it was, you know much better than to push anyone unless your life is in danger, and I know for a fact that your life was not in danger. So I think you and Mommy are going to go have a talk about this."

Olivia reached into Alex's purse and retrieved the hairbrush. She took Erin by the hand and led her over to a park bench several feet away where she sat down and pulled Erin's shorts down, bending the naughty little girl over her lap and spanking her panty-clad bottom. Unlike before during Erin's birthday spanking, these were not light, playful spanks, they were hard spanks. When Erin was crying freely, Mommy pulled down Erin's purple panties and picked up the hairbrush, bringing it down sharply. This was not the first time that Erin needed to be dealt with for pushing, so obviously a stronger lesson was necessary. Erin quickly began to sob, her bottom red and sore. After a while, Olivia put the hairbrush aside and picked Erin up to cuddle her.

"There, there. It's all over and forgiven, sweetie. That's my good girl." Olivia cooed lovingly.

When Erin was calm, Olivia gently pulled up Erin's shorts and panties and gave her another hug and kiss before leading her back over to their little gathering, putting the hairbrush back in Alex's purse while Erin received a hug and kiss from Mama, Daddy, and Auntie Amanda.

"I'm sorry I pushed you, Kat." Erin apologized sincerely, rubbing her sore bottom.

"It's okay, Erin. I love you." Kat smiled and gave her cousin a hug.

The little ones sorted through their Easter eggs, marveling over the candy, money, and small trinkets hidden inside them. Without being told, Erin gave Kat the egg that she had taken from her. Soon, the party was over and Nadia, Kimmy, and Diana left the park to go home. The four adults cleaned up from the party and loaded Erin and Kat back in the car. Erin squirmed a little in her seat, but overall it had been a great birthday and Erin knew she was loved.
