I am having trouble with 45 minute naps like lots of people. DS is 3 months old. I have had some success with extending naps by putting the dummy in at around 35-40 mins. It doesn't work all the time but we have had some naps now that are 2 hours, which he hasn't done for about 3 weeks! Hooray! My questions are: 1. is this going to create a problem later on with him needing the dummy to get back to sleep? 2. If I do this for a few times, will DS eventually learn how to go back to sleep without my help and self-soothe? Thanks
