My little guy has been cluster feeding in the evenings since about 1 week old. Usually from 6 p.m. to 11 p.m. he eats and eats. Luckily he sleeps 4 to 5 hr. stretches at night. I'm concerned because I go back to work in less than 2 weeks and I'll be working from 9a to 930p three days a week. My BF will be home from work to take care of him. Will all that bottle feeding affect my suppy? Will he always continue to cluster feed like this?
