Maybe Baby 2

We meet the two couples again: Cecilie and Andreas, and their son Leo, and Liv and Malte, and their daughter Sille. Both children are now 2 years old, the families still keep in touch, but live very different lives. During a medical examination, it is revealed that the two babies were never swapped. After the shock subsides, the two families decide to move in together in a collective at Andreas and Cecilie's place, so both sets of parents can be with both children every day. However, soon the couples' very different views on lifestyle, decor, eating habits, and parenting methods become apparent, and the two families struggle to live under the same roof. Cecilie feels much more attached to her biological daughter Sille than to Leo, and she decides to pursue custody of Sille behind the backs of the other three parents. Cecilie realizes she has acted wrongly, but it is too late, and her selfish project is exposed. The collective falls apart, Liv and Malte move away with Sille, and Cecilie must now fight to be forgiven and find a solution that everyone can live with.
