My son is 10 weeks old. How often should he be eating? He sleeps 8 hours a night. Our schedule now is 7:30 am, 11:15 am, 3:00 am, 7:15 pm and 10:30 pm. Occasionally if he is fussy, I will feed him at 5:30pm. Ever since he has started the 8 hour sleeping. I have been getting clogged ducts. Is this related to the decrease in feedings?
