Cultural Tip
In many Spanish‑speaking countries "peque" is an informal, affectionate way to refer to a child or a loved one; it’s perfect in casual conversation but might sound too familiar in a formal medical setting. Also, because dairy allergies are common, restaurants often ask "¿Tiene alguna alergia?" and you can answer with this sentence.
