Babies with RSV may also have no energy; act fussy or cranky; be less hungry than usual.

Varies, cough/wheeze. It varies considerably, but RSV has been associated with cold symptoms, ear infections and wheezing/cough. Your doctor may order a test to determine whether your child has rsv. Treatment with a humidifier and keeping the nasal passages clear with saline is helpful.
