Millie Inbetween is a British children's sitcom series broadcast on CBBC and starring Millie Innes. The first episode premiered on 1 October 2014, with the final episode airing on 12 December 2018. It focuses on 12-year-old Millie and her 15-year-old sister whose parents have recently split up. In August 2019, Richard Wisker confirmed that he, Tallulah Greive and Theo Stevenson would reprise their roles from Millie Inbetween in an iPlayer sitcom Flatmates, aimed at an older audience.


In March 2014, BBC commissioned a new 13-part series called The Millie Show. The show name was then changed to Millie Inbetween. It was filmed in Dumbarton, Scotland at the River City Studios, in Northern Ireland in the BBC Blackstaff Studio Complex, and at local locations that resemble Glasgow.


Series 1

Millie McDonald (Millie Innes) is a 12-year-old girl who lives with her 15-year-old sister Lauren McDonald (Tallulah Greive). Their parents have split up, so the two sisters are constantly swapping living with 'Mum' Sharon, (Hannah Jane Fox) and 'Dad' Tony (James Bachman). Millie loves the upsides of her new family set-up; two Christmas celebrations, two birthdays, and two bedrooms. However, the downsides are more tricky to come to terms with, as her parents start new relationships. The parents' new partners have children, too - and they all want to move in. Sharon has a new partner called Mike (Jeremy Edwards), who has a son called Craig (Theo Stevenson), who is a nightmare. Tony meets a new partner called Amber (Jaye Jacobs), who has 2 children called Fran (Mya-Lecia Naylor) and Jake (Marley Lockhart).
