My newborn only eats 6 times a day but he eats a lot. He is breastfed by the way... And he is 2 weeks old?

Good for him! Every baby is different, in terms of appetite and growth. As long as his doctor is happy with his growth and development, then what your baby's doing is working for him. My son nursed for 90 minutes each feeding and gained 1 lb. Per week for the first 8 weeks! so it sounds like your son is a very good breastfeeder-keep up the good work!
