Is it ok that my baby is a slow eater?

Growth curve? If your baby is gaining weight appropriately and reaching his or her developmental milestones, that is the most important. The only concern i would have is if the baby was a slow eater because he or she had to come off the breast or bottle frequently to catch their breath. Other than that, sounds ok.
Yes. Sure! most people eat too fast. Slow down, enjoy the meal together!
