Review on Stay Warm and Cozy: 3M 8T Cotton Thermal Underwear Pajama for Boys' Active Lifestyle by Michael Welborn

Very cute set. My son has been wearing it for 4 weeks in size 3-6 months and it fits him well but it was manageable. In the attached photos he is 11 weeks old and the other 4 weeks. This is a light green color. I want them to make white or oatmeal or black. The fabric is soft and stretchy, but the head opening isn't very wide, so you just need to stretch it a little for big-headed kids. Great for big kids, the legs are nice and long. Pants can be folded down when they are small and then pulled up as they get older and fit better. I would say a size 3-6 would be quite suitable for a size 0-3 but I'm not sure it will fit,
