I think my 3.5 month old DS is starting to use me as a pacifier. He has always loved nursing b/c of his reflux. It seems to make him feel better. He's now on meds that are helping a lot. What are the downsides of being his pacifier? Also, he often wants to nurse to sleep. At night we usually put him down drowsy but he likes to nurse before napping. Is this a problem?
