Jazmin Watters, 5, was Tasmania's smallest single live birth

She was 11 weeks premature and believed to be Tasmania's tiniest-ever single birth.

Her first few months in the world were stressful for her entire family with long periods of time spent in hospital wondering if she was going to be OK.

The tumultuous time included a trip to Melbourne where surgery was required to treat a growth on Jazmin's throat.

Now five years later, she is happy, healthy and preparing for her first day of Kindergarten.

Jazmin's mum, Sharni Watters, is quite understandably a little bit nervous about her baby going off to school.

"[It's] exciting and nerve-wracking," Ms Watters said.

"With her, right from the start I have been very overprotective, so every little thing that she does is a huge thing for me," she said.

"Spending a day with her great grandparents is very hard, I have very bad separation anxiety."

Ms Watters said Jazmin's school had been really helpful with helping to prepare for the transition.

"They have been really supportive and if I need extra time to say goodbye they are more than happy to let me have that," Ms Watters said.

"They have just been really good."

Jazmin however wasn't worried at all about the transition into school. She was just excited to be going.

"I'm excited for homework," Jazmin said.

"[And] I'm excited to make friends."

"For the last three months she has been chanting 'I'm going to school soon'," Ms Watters added.

Great grandparents Ian and Sandra Watters were also preparing for Jazmin to take the next step.

Jazmin has spent large parts of her life living with her great grandparents so they are as invested as anyone else in her first day of school.

"It is another step in the journey - one we didn't know if it would come," Mr Watters said.

"We were there for her birth, we will be there for school too," Mrs Watters added.
