Mum Carly (left) filmed her daughter Myla's (right) reaction to seeing her little sister for the first time

A mum expecting her second child has captured the adorable moment where her two-year-old daughter first saw an ultrasound scan of her little sister (VIDEO BELOW).

The home video shows young Myla I'Anson, kissing and hugging the TV screen as she watches her unborn sibling wriggling around in her mother's womb.

And then things get really emotional as Myla bursts into tears and mum Carly tries to comfort her. 

"I love her so much"

Myla mumbles that she "loves" her baby sister and "misses" her.

"'Oh darling, it's OK ... you're going to see her soon," Myla's mother says from behind the camera in a bid to comfort the toddler.

Wiping tears from her eyes, Myla sobs:"But I love her so much."

Viral video

The heartwarming video has gone viral since it was uploaded last week, amassing more than 55,000 views on Facebook and nearly 40,000 on YouTube.

Carly went to have her 16-week scan last week, and was filming the video on her phone to show it to her family when Myla started hugging the screen and crying.

Carly, 27, said: "I really wasn’t expecting it. It made me well-up, but I was laughing too because it really affected her.

"I love her so much" - the two-year-old's reaction

"A proper girly girl"

"It was heart-warming. She is quite an emotional child. I lost my mum when I was pregnant with Myla so she never met her grandma, but when she sees pictures and videos of her she gets really upset."

Carly explained that Myla had always been "adamant" she was going to get a sister.

She added: "She's a proper girly girl and she loves all of her princesses and everything pink. I will definitely show her the video when they're fighting and pulling each other's hair."

"Very excited"

Carly's second baby is due on November 4 and the expectant mother said Myla is "very excited" to meet her sister.

She continued: "She’s already decided she's going to give up her dummies to give them to her. She's keeping and saving lots of things and toys to give to her when she's born.

"She's also decided we have to call her Snow White. It was Aurora last week so we’ll probably have to name her Ariel or Elsa next week."

"Pulls at [the] heart strings a little bit"

Myla's father Chris, a car fitter, said that her excitement "pulls at [the] heart strings a little bit".

He added: "We did have a chat about how she'd react if we were having a boy but it just would’ve meant that he'd have to play princesses with her at some point in his life."
