Stop Mewling, Squirrel!

The Znamínek family, who live in a beautiful submontane village, are expecting a child. Mum and dad would like to have a boy but their five-year old daughter Kačka is looking forward to a little sister. Kačka is a perceptive child with a colourful imagination. Her games are influenced by the fairy tales told to her by her mum. The family brings two boys - twins - from the maternity hospital. The mum does not know what to do first and she thus cannot tend to Kačka as before. Kačka fools herself into thinking that the parents do not love her any more because she is not their "real" daughter. Her disappointment leads her to ill-considered conduct: she does not want to help mum, drinks up the brothers' puree, hides their bath towels and vests under a wardrobe, runs away with a spread which should protect her brothers from insects and bees and even kidnaps one boy and takes him to the forest in a doll's pram. As a punishment, she must kneel on peas several times. The parents eventually place her in a kindergarten. The girl runs away and at dark, arrives at her grandparents who live in a distant village. The kind-hearted grandmother and granddad convince her that she is wrong. Kačka, pacified, then leaves home with her father. She takes a liking to her little brothers and begins cherishing them lovingly.
