In December 2019, Toby Leung (梁靖琪) gave birth to a baby son, Roman for her husband Jonathan Sze (施雋賢). Within 100 days, she shared photos of her baby on her Instagram account frequently. On 2nd February 2020, Toby uploaded another photo of herself smiling while breastfeeding Roman.

In addition, Toby shared her knowledge about breastfeeding which helped to increase the bonding with her son and improving his health. She pointed her body was a miracle as there was enough milk for her son to drink everyday, and her main job was to pump milk and feed him. Toby revealed one of the purposes for pumping milk was to allow her husband to feed Roman so as to increase the bonding as well. Lastly, she showed another photo of Jonathan feeding Roman with milk by using a milk bottle and it was full of warmth.
