Catherine, who plays Eva Price in the ITV soap, welcomed Alfie on 18 March and the new mum has been besotted ever since.
Over the weekend (18 April), Catherine shared a snap of her fiancé Tom Pitfield holding Alife in a baby carrier. How adorable is that photo?!
Captioning the snap, Catherine said: "Daddy Pickle and baby pickle trained mummy today. @TP_PTfitness and Alfie #babygymwarrior :-)."
If Alfie is going to take after his personal trainer dad Tom, he'll definitely be one active kid!
Little Alfie has also been paid a visit by Catherine's Corrie co-star Antony Cotton.
The actor, who plays Sean Tully, couldn't have looked happier as he held the newborn in his arms. Commenting on the photo, Catherine said: "Cuddles with Uncle Antony @antonycotton xxxx."
Just last week, Catherine and Tom enjoyed a night out at the Palace Theatre Manchester for a preview of Jesus Christ Superstar.
