have baby blankets from my past weanlings/yearlings. Let me know what size you need for sure. Also have nylon breakaway halters that will fit a yearling. I have a burgundy and a navy. Blankets that I have start at 48" and up. Maybe I have the right size for your kiddo. My warmbloods outgrow these things so fast so they are all in excellent condition.
I have a Blue Brake away halter fit my yearling arab stallion! Its also adjustable around the nose and the head, Good condition only used it for the trailer so its in perfect condition!!
Let me know I can get photos!
