Caring for Your Our Generation Doll


Sia arrives with her hair pulled back in two ponytails, but you can style her hair in a lot of different ways!
First things first - haircare for your doll will be easier with the proper tools!
For dolls like Sia with curly hair, we recommend using a wide-tooth, flexible comb and always working with very small sections at a time.
You may also need a small spray bottle filled with water. The best kind to use will be able to spray a very fine mist (instead of a strong jet).
Second, make sure to avoid heat and styling products on your doll's hair (and body)! Heated styling tools like hair dryers or straighteners, and products like gels or mousses, can permanently damage your doll.

We recommend brushing curly hair very gently at the ends. It will help to preserve the curls if you start by combing with your fingers instead of using a brush. If her curls are falling flat, you can divide the hair into small sections, lightly mist with water, combing the section with a wide comb or your fingers, and then very tightly twisting the section into a tight spiral. You may wish to pin it in place to let it air dry. You can also do the same process but use very tight braids instead of spirals. Whichever method you use, please be gentle with curly hair!

Styling curly hair is a lot of fun! You can braid it, put it into ponytails, do a half-up / half-down style - the only limit is your imagination! Styles that don't require the hair to be strongly brushed will help keep the original curls in place longer.

Important Tips

OG Dolls are always ready for fun and adventure. Just remember - the BEST kind of adventure for your OG Doll is in your imagination!
Your Our Generation doll has a cuddly, soft body that should not get wet. Pretend swimming is ok! But please do not submerse your doll in water.
OG Dolls love pretending to play on the beach, but please make sure not to let your doll sit in the sun for too long…exposure to heat of any kind can cause serious harm to your doll!
We know you will do everything you can to keep your doll happy and healthy.

    Hi OG. I really want the Sia doll because she looks just like me and we both love science and the colour purple. However, I live in Australia and I can’t find a place that sells her. I looked online and noticed that Kmart (an Australian store) sells Sabina but I don’t know if they also stock Sia. Please help me get the Sia doll!

    • Hi there! We’re so happy that you found a doll who looks just like you! Sia is a great doll and we know you would love playing with her. The best thing to do would be to check with Kmart and find out if they are planning to carry more stock of Sia, otherwise you may be able to find her online on a website such as Amazon! We hope it all works out!

    I am not sure why only one of the twin dolls come with half of the necklace. The other half should be with the other twin. It even shows the twins each getting half of the necklace in Chapter 12.. I have red headed twin daughters and was SUPER excited to get them these twin dolls, but they are upset that only one doll came with the necklace. Also, the book has multiple errors when it comes to who is telling the story. If this is Sabina telling the story, it should not say “Sabina showed me her gift?” It should say “Sia showed me her gift.”

    • Hi Leah! We’re so glad you love the twins, and we’re sorry for the confusion about the necklaces. All of our twin doll necklaces were discontinued in 2018, so newer versions of the dolls no longer include them. Some of the older models which include the necklace are still being sold by our retail partners until stock is eliminated, which may be why you received one. We are aware of the typographic errors in the Sia and Sabina storybook and have reissued a corrected version – thanks for bringing it to our attention! We hope that regardless of the necklace issue, your daughters continue to have fun with their Sia and Sabina dolls!

    I have just received Sia for Christmas to go along with the Sabina doll I have! I am a huge fan of OG and have five dolls including one boy doll. The microscope is very cute! My only problem is that Sia and Sabina did not come with the twin necklace I saw in the picture. I am very disappointed because the twin necklace looks very cute! Other than that Sia is a great doll to add in my collection. She is my new favorite doll… so far! I hope to see more amazing dolls! Thank you our generation!

    • Hi there! We’re so happy you love OG dolls and your new Sia doll! Unfortunately, all the twins necklaces have been discontinued, which is why we no longer show pictures including the necklace. Maybe it would be fun to make matching necklaces that you can give to your dolls? Have fun!

    I love sia her hair is beautiful and so is her sister however, her hair gets really tangly fast and it’s hard to brush because of her curls. Please help… other than that she is perfect I recommend her!

    • Hi Isabella! Did you know that you can find hair care tips for Sia on her page under the tab called “instructions”? We hoe this helps you care for Sia’s hair! 🙂

    My daughter is enjoying her new doll: her reward for summer reading. We immediately started the included book this evening. Unfortunately, only four chapters in, we (I) have already found 3 errors of the same type. In chapters from Sabina’s point of view, she will refer to “Sabina,” when clearly it should say “Sia,” as Sabina is the one telling the story.
    We have never read a book from Our Generation, so I don’t know if this is common, but I hope they start doing a better job with book quality. Reading is so important and our children deserve books without error.

    • Hi Meredith! We agree, reading is VERY important! We’re happy that your daughter is enjoying her Sia doll, and we’re very sorry about the typos in your edition of the book. This was noticed and corrected by our editorial team, however some products still in circulation seem to have the older version of the storybook. Please get in touch with our customer service at and we will work on getting you the corrected version of the book! Thanks for reaching out and we hope you continue to have fun with Our Generation!

    I think sia is so cute I have Sabina as well I have a large collection of dolls and accessories but I’m sad to say that when I got her out of the box her leg was popped out so every time I play with her I have to pop it back in..

    • Hi Hermione,
      We’re sorry your Sia doll had a problem with her leg! Sometimes there can be a mistake in the manufacturing. When things like this happen, the best thing is to bring the doll back to the place where you bought it and exchange for a new one. But if you’re still happy playing with Sia and helping her with her leg, then that’s okay too! We’re so glad you love Our Generation dolls!

    She’s is a really pretty doll and comes with super cute outfits. But her hair is hard to brush. The glasses look a bit small. The microscope battery didn’t work so we had to change it. The head band fits really well and looks cute with any outfit. Defentaly recommend.
