I bought this as a baby gift for my friend. However when I got it, it looked like it would fit my almost 7 month old even though it was listed as 0-6. I decided to keep it for my baby instead because by the time my friend’s baby would fit in it, it would be too hot. I really love the color of it and it’s super stretchy and soft. But definitely runs way too big. The neck of it is pretty big too as you can see on my baby. I think she will be able to wear it through fall and winter though! I would say sizing is more 6-12 instead of 0-6.It’s definitely a little bigger but he will fit in it longer. I’m obsessed. So cute and soft! Well made. Ordering more colors!Fits fine, but when we received it the stitching on the shoulders had already gone leaving a large hole.
