And the polyamorous family’s adorable two boys have melted hearts with their longing wish to have a baby sister during a pregnancy reveal.
Courtney Cantano, 27, from the US, filmed the heartwarming moment she told her sons how to read a positive pregnancy test confirming that another sibling on the way.
Sons Dario and Anthony, eight and three, wore beaming smiles after hearing one of their mums was expecting a new addition to their family, during the treasured moment in January.
The kids who are completely adjusted to having two mums and a dad, had been asking their parents for another brother or sister for over five-months - with their preference strongly aimed towards a sister.
Courtney, who is carrying a boy, said: ‘The boys are very excited about the baby’s arrival, all three boys will get along great and we will make sure to give them all the attention they need.
‘Another benefit of having three parents is they get lots of love and attention, they’re also surrounded by a lot of grandparents, family members and friends that spoil them too.
‘Both boys really easily transitioned into a polyamorous family, they call me 'purple mum' and Michelle 'blue mum' because of the colours of our hair.
‘I fell in love with them and they fell in love with me, they naturally started to call me Mum within six-months
‘I’m very lucky to have both my husband and wife, Michelle and Matthew, around to offer extra help with the baby.
‘After showing family and friends, everyone thought the video was cute and very sweet - we are all very lucky to be surrounded by a lot of love and support.’
