===Sleeping===
Placing an infant to sleep while lying on the belly or side rather than on the back increases the risk for SIDS.<ref name=Moon2012/><ref>{{cite journal | vauthors = Carlin RF, Moon RY | title = Risk Factors, Protective Factors, and Current Recommendations to Reduce Sudden Infant Death Syndrome: A Review | journal = JAMA Pediatrics | volume = 171 | issue = 2 | pages = 175–180 | date = February 2017 | pmid = 27918760 | doi = 10.1001/jamapediatrics.2016.3345 | s2cid = 25569308 }}</ref> This increased risk is greatest at two to three months of age.<ref name=Moon2012/> Elevated or reduced room temperature also increases the risk,<ref name=Moon2007>{{cite journal | vauthors = Moon RY, Horne RS, Hauck FR | title = Sudden infant death syndrome | journal = Lancet | volume = 370 | issue = 9598 | pages = 1578–1587 | date = November 2007 | pmid = 17980736 | doi = 10.1016/S0140-6736(07)61662-6 | url = http://adc.bmj.com/cgi/content/short/46/248/579-a | access-date = 14 February 2019 | url-status = live | s2cid = 24624496 | archive-url = https://web.archive.org/web/20210829073529/https://adc.bmj.com/content/46/248/579.2 | archive-date = 29 August 2021 }}</ref> as does excessive bedding, clothing, soft sleep surfaces, and [[stuffed animal]]s in the bed.<ref>{{cite journal | vauthors = Fleming PJ, Levine MR, Azaz Y, Wigfield R, Stewart AJ | title = Interactions between thermoregulation and the control of respiration in infants: possible relationship to sudden infant death | journal = Acta Paediatrica | volume = 82 | issue = Suppl 389 | pages = 57–59 | date = June 1993 | pmid = 8374195 | doi = 10.1111/j.1651-2227.1993.tb12878.x | s2cid = 44497216 }}</ref> [[Bumper pads]] may increase the risk of SIDS due to the risk of suffocation.
