Lisa Wilkinson pens a letter from one school mum to another.

About their children’s first and last days at school.

It’s that time of the year again – where parents are dropping their kids at school for the first time, re-signing up for canteen duty or getting ready for the final 365 days of school runs. It’s back-to-school time.

For every parent this signals a different thing, a different stage in life and a different step in to the future.

So Co-Host of Channel 9’s The Today Show, Lisa Wilkinson (who’s youngest is starting year 12 this year) took to writing a letter to Opinion Editor of the Daily Telegraph, Sarrah Le Marquand (who’s eldest started kindy this year) about the journey she is about to face – as a school mum.

The letter was a personal account from one mother to the next, but is one that will resonate with parents dropping their kids at school everywhere.

In the letter on The Daily Telegraph, Lisa spoke about how fast time flies and how often you wonder where the time has gone.

After writing about letting go of her daughter's hand, to the peer groups, right down to Pythagoras's thereom, Lisa explained that parenthood is constantly about learning to let go.

"And now, as we hit the final stretch in this path to independence, I am hit by the question all parents face at such a momentous time — where, oh where, did all those years go?" She said in the letter on the Daily Telegraph.

She spoke of the wise words from two of her sister-in-laws, one who told her that the journey was a roller-coaster and explained that the, "role of the parent is to be the flat road of quiet support." And the other who made her realise that during the stressful times in school - as a parent - it is about letting your child study while you help them out with the rest of life (like cooking and cleaning).

Lisa ended the letter in the Daily Telegraph with some wise words of her own. She explained to Sarrah that in the end your child's final mark in school is not the be-all and end-all for life. It is simply another fleeting moment that will come and go as though it almost didn't exist.

She says in the letter, "Cherish these times: they won’t come again."
