Viewers of Coronation Street are furious that Sinead's mum and nan are currently missing from her cancer storyline.
Last year, Sinead was diagnosed with cervical cancer whilst pregnant with her son Bertie.
She decided not to have treatment in order to protect her unborn child.
After prematurely giving birth to Bertie, Sinead had treatment straight away and earlier this year she was told that her tumour had shrunk and showed no signs of spreading.
But unfortunately just months later Sinead discovered a lump on her neck as she prepared to marry Daniel Osbourne.
Her worst fears were later confirmed when the doctors told her that the cancer had spread and she had months to live.
She was recently told the hospital were stopping her treatment and she only had weeks left.
Over the last couple of weeks, viewers have seen Sinead get more ill but she has had the support of her family.
Where is Sinead's mum?
However there are two important characters who haven't been seen: Sinead's mum Arlene and her nan Nancy.
Arlene and Nancy have made numerous appearances between 2015 up to September 2019.
They were last seen last month at Daniel and Sinead's wedding celebrations but haven't been seen since Sinead was told she didn't have long to live, leaving viewers wondering where they are.
Coronation Street airs on Mondays, Wednesdays and Fridays at 7.30pm and 8.30pm on ITV.
