When mama goes out, she tells the eldest daughter to mind her four younger sisters and the dog. She doesn't.
It's an amusing domestic comedy to appeal to the middle class, particularly when one of the toddlers gets out of the house to go to the nearby farm, which has plenty of chickens, and a goat.
The essentially middle-class attitude of this movie -- you can't leave your children alone for a moment -- was typical of very early British films, although it was dying down by the time this movie came out; the majority of the market for films was the lower classes, and their concerns and amusements formed the basis of most films, at least until longer films came in, demanding more structure than could be attained in half a reel.
