We love these pants, they are super comfy, the elastic is great and very stretchy... in our case the only pair of pants 0-3 months that still fits my 2 mo old (chunky monkey for his age)... the cuff at the bottom is great for keeping him warm and when we first got them as a newborn and they were too long we cold easily fold it up without it looking weird. They've fit so well at so many different stages of his growth I can say these are his most used pair of pants, they are so versatile, and stretch to fit comfortably he will probably even be able to use them past the 3 mo mark when in everything else he has been using 2 sizes up! The thickness is just right too, not too hot (we live in a warm climate) and yet warm enough to do double duty as pj's or to wear them at night. Believe me if yo order them you will definitely get tons of use out of them! The only bad thing I have to say is in the grey black pack the "black" color is not as black as I would have liked more of a dirty brownish/black so I usually do not pair it with other black clothing which really makes you notice it and just use them with bright colors so it's not a problem.
