Merlin sleep training suit size small

Merlin suit. Transition sleep sac. To help transition from swaddled to open arms sleep sac. Thicker heavier material to help decrease the startle reflex and help transition to a regular sleep sac. Size small. Fits 3-6 months approx or 11-20 lbs. some staining around neck. I never tried to treat it, just washed and air dried. Most likely can be treated, I just don’t have time since I’m going through all our baby stuff and it’s a significant amount. Prices to sell per condition.
