Infants are unable to regulate their body temperature in a normal way until they become toddlers. Because of this, it can be challenging for new parents to know how to dress their baby or what to set the thermostat at in order to keep the nursery just right.
The temperature of a baby’s nursery should be kept anywhere between 61 and 68 degrees Fahrenheit. According to the Mayo Clinic, keeping the room warmer than normal isn’t necessary; any room a baby spends time in should be kept at a temperature that’s comfortable for the average adult.
Rather than turning the thermostat up during colder months, you should dress your baby properly. This usually means one layer more than you would wear. A T-shirt plus a footed sleeper is all most babies need for sleeping. An overdressed baby sweats; remove a layer of clothing to help keep him comfortable.
Sleeping in an overly warm room, whether in the summer or in the winter, is considered a risk factor for sudden infant death syndrome (SIDS). Air flow is as important as a moderate temperature, so make sure the room isn’t stuffy. Open the window a crack or keep the door open.
