Welcome to Crafty Little Slings.
I make Half buckle slings and Pods. My Half Buckles have an unstructured waist and high body panel making it suitable from around one month (though I'd always recommend a stretchy sling for the first few months) up to 3 and beyond. The Pods have a large panel and wide wrap strap shoulder straps and are suitable from newborn to preschool.
Please take a look through my pages and drop me a line if you have any questions!
