Inga is a stomach sleeper...she will not go more than 5-10 minutes on her back or side, but will sleep forever on her stomach.
Last night I swaddled her and laid her down on her back. When I woke up more than 5 hours later, she had rolled herself onto her stomach--still completely swaddled! I finally woke her up to nurse because I was bursting. So my quandary is--do I let her sleep on her stomach? I'm reluctant to do so because of the increased risk of SIDS.
At least Zari is more than happy to be a napping surface.
