Hand foot and mouth in infants and young babies can start with a fever, fussiness, poor feeding, or seeming more tired than usual. Some babies develop painful mouth sores before a rash appears, while others get small spots or blisters on the hands, feet, diaper area, legs, or around the mouth. In a 6 month old baby or a 1 year old baby, symptoms can be harder to spot because they may not be able to show where it hurts. Parents often notice drooling, crying with bottles or nursing, waking more often, or refusing solids.
Hand foot and mouth fever in babies may come before the rash. Your baby may seem clingy, irritable, sleepy, or less interested in feeding.

Yes, hand foot and mouth is contagious in babies and commonly spreads through saliva, nasal secretions, stool, and contact with contaminated surfaces.
