My daughter is 9 months old, 22-24 lbs and she has dark circles under her eyes(pink to light purple in color). It is not all the time but frequently. She is a very good eater. I mostly feed her organic fruits and veggies during the day and she tends to have a little of whatever her dad and I eat. She has lots of energy and is on track with her development. She isn t much of a sleeper. maybe an hour of naps during the day and 8 hours at night. Just wanting to know if I should be concerned.?
