Hand, foot and mouth disease (HFMD) in Babies & Toddlers: Signs, Care, When to Call

What it looks like

Painful sores or ulcers in the mouth, plus flat or raised red spots, sometimes small blisters, on palms, soles and often the bottom.

On brown and black skin, redness may look purple, grey or darker than surrounding skin; texture (raised, rough, blistered) is often the better clue.

What causes it

Enteroviruses, most often coxsackievirus. Spreads through saliva, blister fluid, coughs and poop.

What helps at home

Offer cold drinks, yogurt or ice pops; avoid salty or acidic food that stings.
Acetaminophen or ibuprofen (ibuprofen only from 6 months) can ease mouth pain. Dose by weight and check with your pediatrician.
Wash hands after diaper changes; the virus can shed in poop for weeks.

General guidance based on AAP, NHS and CDC advice, not a diagnosis. If your gut says something is wrong, call your pediatrician or nurse line. You never need permission to seek care.

Questions parents ask

Can my child go to daycare with HFMD?

The CDC and NHS say children can usually return once they have no fever and feel well enough, even if spots remain. Check your daycare policy, as some ask you to wait until blisters dry.

Can adults catch it?

Yes, though adults often have mild or no symptoms. Handwashing after diaper changes is the best protection.
