Frequently asked questions about MARY by sticklett

Why does MARY work with her own clothes?

Our research showed that close physical contact and the position of the measuring device on the body determine the accuracy and reliability of the measured values.

Attachments using adhesive strips and straps are not suitable for children and are unthinkable for us. Attaching to traditional clothing or diapers that loosely fit the body is too prone to errors.

Based on this achievement, we chose the approach in combination with sleepwear and underwear that includes a special cut construction so that the measured values ​​provide a high level of accuracy and the clothing remains suitable for everyday use, ecological, washable, breathable and comfortable to wear. The ergonomically shaped measuring device, disguised as a beloved ladybug, fits hygienically and child-friendly on clothing, sits and stays close to the body in the correct position and ensures reliable functionality.

My child is a stomach sleeper: Does the ladybug bother my child when he sleeps?


Mary is soft and ergonomically shaped and adapts to the body so that it is not perceived as a foreign body when worn. Your child can sleep on their stomach without being disturbed by Mary.

However, if you don't want your baby to sleep on your stomach, MARY can call you via your smartphone as soon as your baby rolls over onto its stomach. According to studies, stomach sleeping, especially in babies, can increase the risk of sudden infant death syndrome.

I'm afraid my child will start playing with the ladybug and take it off his clothes. What can I do?

Mary should generally not be used as a toy. Since Mary was developed to be very child-friendly, she naturally entices them to play. We have therefore come up with a little story that can be lovingly explained to the child, Mary. This story with Mary is delivered to you as a small picture book and can be read aloud during the bedtime story ritual. Mary is supposed to be a little ladybug friend for children who looks after them at night or when they are not feeling well and calls their parents immediately when they need her. We tested the story with many children. In our testing, the children were happy to have Mary looking after them and Mary voluntarily stayed on the garment.
