Martha Kalifatidis has defended her decision to continue to live with her ageing parents as she raises her two young children. 

The Married At First Sight star and her fiancé, Michael Brunelli, 35, reside in Melbourne with her parents, Mary and Theo Kalifatidis.

The 37-year-old opened up her Instagram to questions from fans this week, and one follower suggested Martha should move out of her family home. 

'It's about time you moved out of your parents' home now you have a family,' the person commented. 

Martha defended her choice, explaining that being close to her parents has a wide range of benefits. 

'Look, I know our living arrangement might not make sense to everyone, but it works really well for us,' she said. 

'We have support, the kids are surrounded by love and we all actually get along (surprise)!

'If this wasn't the case, we probably wouldn't be here!'

Martha went on to say that her son, Lucius Brunelli, loves getting 'so much attention' from his grandparents while she's been busy with her new baby, daughter Sunday.  

'I think it's helped him not feel pushed aside during such a big transition,' she said. 

The former reality star explained she appreciated 'being able to shower, blow-dry my hair and feel somewhat human some days,' as a new mum. 

'I actually think support makes you enjoy parenthood more,' she said.

'You're less burnt out, less overwhelmed and less likely to resent the hard parts because you're not doing everything completely alone.'

Martha and Michael welcomed their daughter in March, and have been settling into life with two very young children. 

The pair have relied on support from Martha's parents since her first pregnancy in 2022. 

Martha battled through hyperemesis gravidarum during her pregnancy with son Lucius, and was hospitalised at the height of her illness. 

'I was so sick. I could not eat or drink anything. There were days I didn't even get up to pee. I lost ten kilos in five weeks,' Martha explained at the time. 

The couple first met on MAFS in 2019 and got engaged two years later, but are yet to marry.
