Ms Ljungstrom said it was "natural" for her to share her labour because she had video blogged her pregnancy. The videos were posted on Facebook page Channel Mum.
She said: "I was always looking for help and advice especially about the big things like labour and feeding that I was anxious about.

"Stories from other real mums I could relate to helped me so much.
"So I decided to share my own to show a real everyday labour that other mums and pregnant woman could follow and see how it went. Birth isn't really like the movies so showing a normal everyday labour story was nice."
The first Facebook Live video, which allows viewers to react to the poster in real-time, was posted from hospital at 10pm on December 21.
Ms Ljungstrom, a director at an advertising agency, told the 86,000 viewers her waters had broke and she was 2cm dialated.

Two hours later she posted a second video, explaining she had been sent home until her contractions grew closer together.
The following morning Ms Ljungstrom had contractions live on camera as she sipped tea at home.
She said: "Sorry I'm having a contraction now. It's not fun this bit, is it? Thank you so much for your support. It's really nice having you all around me."

She added: "Don't let me get pregnant again. If I ever say I want another baby I can watch this back. I can't stop talking I'm so nervous. I'm not going to do through the hard bits because I wouldn't be able to be so calm."
A few hours later the tearful mother-to-be posted a fourth video as she walked back into hospital with husband Henrik, saying she was upset to leave her sons, Freddie, six, and Finn Barnaby Bo, three, at home.
Less than 12 hours later she posted a final video showing baby Evelina in her arms, which was viewed more than 200,000 times.

Speaking after the post she said: "I think our social networks are amazing support networks - especially in the online motherhood world.
"So I just felt I was chatting to a bunch of mums who all had my back and were giving me words of encouragement.
"Emotionally it made me feel braver and more hopeful as I had the encouragement of women I knew had been there and done it. I got some great advice and read all of it.
"It felt like I had a whole village of women with me in spirit."
