I really liked this item when I first received it, but have since been unable to wear it. I purchased the item at 6 months and by 8 months (didn't grow that much) they became too tight. I would recommend purchasing a size larger than what you usually wear, but be careful because parts may fit bigger or smaller depending on your body type. For instance, the legs of the small fit me still, but the belly is too tight and literally gives me contraction like feelings. So, if you end up 'all belly' you may not be able to wear this item for too long. However, they are comfortable.
