‘Where are you going sir?’ someone was heard asking the baby, who sat down in defeat.

‘Let’s go back to your playroom,’ he was told, as he looked sweetly into the camera.

The doting mom wrote her new catchphrase,  #Slivingmom, under the video.

It’s a combination of ‘slaying and ‘living, (your best life), i.e. being successful, glamorous, etc,’ according to the Collins Dictionary.

Paris’ fans were thrilled with the little one’s progress.

‘Educator here! Crawling is great for brain development! Using the left and right side of the brain together! Go Phoenix!’ wrote one follower.

‘Get ready for that cardio 24-7. They get quicker now,’ advised another mom.

They added to their family less than a year later, when the couple announced the birth of their daughter London in November.

Both children were born via surrogacy and she and her husband kept both pregnancies secret.

‘My life has been so public, so out there,’ she told Romper after Phoenix was born, ‘I didn’t want my son to come into this world with any negative energy. I’m really happy I did it that way, just for Carter and I to have that journey together without the outside world chirping in.’

Paris’ younger sister Nicky, 40,  and mom Kathy, 64, were aware the couple were expecting London, whose birth was announced at Thanksgiving when the infant was introduced to her extended family.
