My daughter turned two in May. She has a deep fatty band or roll on the front side of her neck. It seems to fade towards the back of her neck, but it's hard to tell. I believe it is asymmetrical and more prominent on her left side. The band has continued to grow along with her since she was little. She had mild torticollis as an infant, which was addressed very late (9 months - 1 year) and still has plagiocephaly as a result of the torticollis. She has graduated from PT for her torticollis.
