Hello PEOPLE.com readers!

Hope you had a wonderful holiday season and are enjoying the first month of 2015. My pregnancy is moving along nicely and the countdown to meeting our new family member is getting shorter and shorter! Seems pretty unbelievable that we will be having another person living here in just a few months.

In case you were wondering, I’ve done nothing to prepare for round two of motherhood as of yet. No nursery, no car seat, no diapers, no name … not a single thing that one would do before welcoming a new child into this world.

Of course this ill preparation has nothing to do with my lack of excitement — I truly cannot wait for the baby to get here! My main focus has been prepping Elliotte and making sure she is handling the upcoming life change in the easiest way possible.

I also blame it on lack of coffee and sushi. And really … having a name is overrated. Right?

You guys completely forgot to mention that your stomach doubles in size by the millisecond with your second baby. I mean, I feel like by the end of this, maternity clothes are going to be too small. When people ask me what month I’m in, their eyes look like they are going to fall out of their sockets! I wish I were kidding. My sensitive soul is trying not to let it get to me and I’m doing my best to keep my eye on the prize. (Baby, coffee, sushi. In that order.)

Elliotte’s excitement for the new baby has not waned at all and I cannot wait for her to meet her new baby SISTER! Yep, that’s right, we are having another girl! We are truly so excited to be welcoming another little lady into the mix — we are knee deep in princesses and tea parties over here so I consider myself an expert on the color pink and all that it entails.

This leads me to my next thought: Apparently the terrible twos aren’t so terrible after all and three is what we should all be scared of. Yes, that’s right, my sweet angel toddler has officially morphed into a threenager.

Unofficial definition: A 3-year-old child who acts as if they are 13.

I wish I had coined this clever phrase (and I wish I could be best friends with the person who did!) because it’s truly fitting. They say the ages of 2-5 mirrors how your child will be as a teenager so consider me afraid.

With a little over a week to go until her third birthday, Elliotte has gotten a running start in the sass department. Some days, she wakes up and she is completely happy with the shape of her pancakes … other mornings, the size of them will send her into a tailspin without warning. Sometimes this will end with her going on a hunger strike, other mornings she will suddenly flip back into her sweet self and start complimenting my fabulous cooking skills.

Don’t ask. I have no clue.

At first, I wasn’t sure how to handle this newfound attitude, but as the days go on, I’m slowly learning some tips on how to keep everyone sane.

For instance, if said 3-year-old wants to change 14 times before leaving for school and ultimately ends up wearing a ripped princess dress, sparkly boots and knotted hair? You simply smile and say, “You look beautiful!” and quickly usher her into the car before she changes her mind.

If there is a parent in the land who thinks I purposefully dressed my child as a homeless princess, they haven’t reached this stage of irrational child yet.

If your threenager puts on a pair of sunglasses and says to you, “I need some privacy, please leave me alone,” you kindly thank them for saying please, slowly back out of their bedroom and let that child be. Asking them to play with you or perhaps enjoy a healthy snack could result in permanent parental termination. Translation: I want a new mommy!

Don’t get me wrong; I don’t let my child run the show by any means. I’ve just learned that picking my battles is key. If my daughter is safe in her room and needs to channel her inner threenage angst, so be it.

If your child often tells you to “stop singing” or “no more talking” whilst in the car, congratulations — you are the proud parent of a threenager!

My favorite is when my daughter decides she wants nothing to do with me and wants to be alone with her dad. “Mommy, you stay home. I only want Daddy to take me to the zoo.” Now let’s be honest here, not going to the zoo on a crowded Saturday afternoon — that is hardly a punishment!

In all seriousness, I love the relationship that she has with Alec, and we are so lucky to have a dad and husband like him in our lives. He is adventurous and fun and lets her eat lollipops the size of her head — it’s no wonder why she disinvites me places.

All joking aside, I wouldn’t trade this diva side of Elliotte for anything. She has little personality bits of her mom and dad in her and some of the things that come out of her mouth keep us laughing for days on end. There is no lack of entertainment in this house!

At the end of a long day, I still get bedtime books, kisses and snuggles and that is truly everything. Keeping a sense of humor is key and once the new baby comes I will remind myself of the finite nature of childhood and how quickly it goes by and try to always keep my girls laughing. Even if it’s through their tears.

Are you the parent of a threenager? Or do you know one and have a great story to tell? Leave a comment below or send me a Tweet @marlasok!
