Bodysuit or sleep sack ? That is the serious question
Newborns placed in a sleep sack were less active and touched parts of their bodies less frequently than those dressed in a simple bodysuit. The scientists suppose that the former may have been more stressed for two reasons: their movements were hampered, so that comforting self-touching was less frequent. This study is published on 17 March 2015 in Scientific Reports.
