• Nursing ulcers on the lips
• Gulping or clicking sounds while nursing.
• Gumming or biting nipples
• Milk leaking from the sides of the mouth while feeding.
• Choking easily
• Frequent releasing and relatching
• Shallow latching
• Long feeding sessions, often with the baby falling asleep mid-feed
• Colic, gas, or reflex
• Poor weight gain or weight loss
• Inability to hold a pacifier in the mouth
