With Children at the Seaside (Bulgarian: С деца на море, romanized: S detsa na more) is a Bulgarian anthology comedy film released in 1972, directed by Dimitar Petrov, starring Georgi Partsalev, Petar Peychev and Ivaylo Dzhambazov. The screenplay is written by Mormarevi Brothers.

The movie consists of two separated stories that are bound by the theme about the summer seaside vacation as well as by the character of the plump teenager Pipsi. This is the second film of the "Childhood series" by Mormarevi Brothers, featuring children's characters in the main parts.

The first segment is named The Dolphin, starring mostly children led by the witty plump teenager Pipsi (Petar Peychev). The kids are obsessed by the story about a mysterious dolphin insinuated by a local fisherman and playboy who tries to tie affair with the elder sister of one of them. The second segment is named The Amateur Photographer, starring one of the leading Bulgarian comic actors, Georgi Partsalev, in the role of uncle Mancho, an aging man who flirts with a young female colleague during a pseudo business trip at the seaside. Unfortunately for them, they are accidentally photographed by the same teenager Pipsi (Petar Peychev) who turns out to be a neighbor of uncle Mancho.

As usual for the films written by Mormarevi Brothers, With Children at the Seaside obtained wide popularity and became one of the classic Bulgarian comedies from the 1970s.
