And it seems they were right to be worried, because this week he takes a turn for the worst while being looked after by Summer Spellman.
Steve leaves his son with Summer while he goes to help eldest daughter, Emma Brooker.
Emma is in the middle of a relationship drama with ex-boyfriend Seb Franklin, and Steve steps in to help.
But things take a worrying turn when Oliver starts fitting while being looked after by the school girl.
Oliver's hospital dash
Next week sees terrified Steve racing his son to the medical centre, worried that something is wrong.
One he arrives, Doctor Gaddas is quick to reassure Steve but tells him to take Oliver to A&E as a precaution.
It's not long before a panicky Leanne meets them at the hospital and she is furious when she hears Steve left Oliver with Summer.
Steve takes on Leanne
Later in the week Steve asks Imran for legal advice about getting better access rights to his son.
However, with Toyah's connection to the toddler, Imran is understandably reluctant to get involved.
Instead Imran hands Steve the number for another solicitor, but it soon gets Steve in trouble.
In a bid to build bridges, Steve asks Leanne and Nick out for dinner at Speed Daal with him and Tracy.
But while things seem to be going well at first, trouble erupts when Steve drops the solicitor's business card.
Leanne demands to know what it is for, and it's not long before the truth is out.
The parents argue over Oliver and Leanne is fuming to realise that Steve is seriously considering taking legal advice.
Is this one fight that Steve is going to regret starting?
