Is a peace lily poisonous in babies?

Yes, peace lilies (Spathiphyllum) are considered toxic to babies and pets if ingested. They contain calcium oxalate crystals, which can cause irritation to the mouth and throat, leading to symptoms like swelling, pain, and difficulty swallowing. It's important to keep peace lilies out of reach of young children to prevent accidental ingestion. If ingestion occurs, it's advisable to seek medical attention.
