Infant T-Shirt runs small but adult shirt runs big!I ordered both adult and infant shirts. I was excited to received them, but I was a bit disappointed with the infant T-shirt size. My son is 18 months old so I ordered 18 months size hoping it will be a little bit bigger on him since he is a small child. He still wears 12 mos old shirt, but this Little Guy shirt size is the same as 12 months old shirt, its nowhere near 18 mos size. I am going to have to air dry it to prevent it from shrinking. Of course, an adult T-Shirt size I got is large and it looks like an extra large size. I guess I will have to wash it and dry it to shrink it. Hope it's all turn out good before Father's Day! Good Luck!
