Embodiments provide a system to detect abnormal breathing by a person, such as a baby, through a piece of clothing worn by the person. The piece of clothing may be adapted to include a sound sensor that can collect breathing sounds by the person. The piece of clothing may also be adapted to include an inflatable neck support that can be automatically inflated without the person's intervention. The breathing sound signals by the person can be processed for determining whether the person breathing abnormally. When it is determined that the person is breathing abnormally, an instruction to inflate the inflatable neck support of the clothing may be generated. Such an instruction can be transmitted to the clothing wirelessly to effectuate the inflation of the inflatable neck support so the person's incorrect breathing posture that causes the abnormal breathing can be addressed.
