Pacifier: to use or not to use

T baby love
My baby is a month old and has trouble staying asleep for long periods now. It's hot and cold. Some days we sleep good, some days I fall asleep with my baby on my chest (often) because night wake ups are often. 
IV been thinking about giving a pacifier but I don't want the attachment and melt downs that comes later. 
What do I do? Anyone have a similar experience?
