Are holiday plants like poinsettia and mistletoe harmful to children?
When eaten in small amounts, most holiday plants will cause minor nuisances, such as mouth irritation or mild nausea, vomiting or diarrhea. However, eating several berries (such as holly berries) can also lead to dehydration and extreme drowsiness in animals and children. Pine needles and other sharp leaves can injure the mouth or throat when swallowed. So, yes, do keep plants out of the reach of children.
