In warm weather, baby just needs a singlet and nappy underneath the wrap. Overheating has been linked with SIDS, so try to keep baby’s sleep environment at a cool, comfortable temperature.
In cool weather, dress baby in a lightweight jumpsuit underneath the wrap. Don’t use a bunny rug or blanket – it can cause overheating. Also be careful not to overheat the house, especially if baby has an infection.
Make sure the wrap doesn’t cover the head, ears or chin. Wraps that are too high can obstruct baby’s breathing and cause baby to overheat.
