Surrogate Sonya has her first ultrasound in Neighbours

Wannabe parents Steph and Mark attend an appointment with Sonya, who's their surrogate mother

It's a big moment for Sonya (Eve Morey), Steph (Carla Bonner) and Mark (Scott McGregor), in Neighbours this week, as the trio head to the hospital for an ultrasound scan. With Sonya pregnant with their child, having offered to become a surrogate mum for the wannabe parents, it's an emotional time for all.

With the arrangement having caused so much drama for Steph and Mark and Sonya and her husband Toadie (Ryan Moloney), who was reluctant for his wife to go ahead with the surrogacy, reaching this point is a major milestone for the trio, who got pregnant during the first round of IVF. But with cracks appearing in both couples' relationships, is the joy of seeing the baby on screen set to last?

It's a big day for Steph, Mark and pregnant Sonya, who attend their first ultrasound appointment.

With Sonya having taken on the decision to become a surrogate mother for Steph and Mark, the sonographer checks to see if the baby is OK.

… and it's good news, the baby is doing fine!

As Steph and Mark take it all in, the couple is thrilled - but will their happiness last? Watch Neighbours on C5 from 23 January at 5.30pm
