Drop-seat pajamas

Drop-seat pajamas, also known as blanket sleepers, footed pajamas or Dr. Denton's, are a warm and comfortable one-piece sleeping garment with long sleeves and legs, sometimes with attached booties, commonly worn by infants and young children in the United States and Canada.

Wide-cut blanket drop-seat pajamas used to be known as hansop in Dutch.

The drop seat

Drop-seat refers to a flap at the buttocks that allows opening without undressing the garment. Traditionally the drop seat closes with buttons, but modern versions often replace the buttons with snap fasteners. The drop-seat feature is designed to allow the person to use the toilet without removing the sleeper. However it is also convenient for parents and other persons of authority (e.g. grandparents or babysitters) to give the wearer, when such punishment is felt necessary, a bare bottom spanking.

For this reason, drop-seat pajamas are also spanking clothing and fetish clothing for spankophiles and sold in web shops such as Bobbie's DropSeats. In addition, such garments are also popular among adult babies.

Spanking artists who have drawn drop-seat pajamas scenes include Sassy Bottoms, Patty and Lawrence Kinden.

Drop seats are also found in union suits.

Web businesses

Several small businesses manufacture blanket sleepers on a small scale, and market them on the web. A list of these follows. (Note that some of these businesses cater specifically to people with sexual paraphilias, and may contain content that some people may find disturbing or offensive.)
