First off, don't freak out about Ayden sleeping on his front. He is almost 3 months old and can lift his head and actually turns it from side to side while he is sleeping. Secondly, we don't put him to sleep like this overnight. At the moment he is still sleeping in his bassinet beside our bed. Up until recently we have had a hard time putting him down to sleep anywhere let alone his own bed. It seems that whenever we get him asleep, as soon as we lay him down on his back in his bed or on the couch or wherever, within 2 minutes he's awake. I decided to try and lay him down on his front one day as he always seems to fall asleep on my chest. Low and behold, he stayed asleep. We have the baby monitor beside us at all times and also go in to his room just to make sure he is still breathing :)
Well this last time I checked on him he had switched the side he was laying on and also started to suck his thumb.
