Can Kat convince her otherwise?
During a Slater family dinner at Kat and Phil's place, Lily loses her temper with crying Charli. She has a full-blown meltdown over her ability to be a good mum and storms off.
Rushing after her, Kat shares her own experience with Zoe and Lily worries she's too young to do this. But Kat insists that with Stacey by her side, Lily can be a great mum.
However, with the pressure mounting, Lily isn't convinced.
