Could Overeating Of Bananas By A Child Be A Matter Of Concern?

hello. today as my family and i were cleaning and preparing for the week ahead it went unnoticed that my 3 yr old had made several trips to the kitchen. she asked for a banana. and i gave it to her while dinner was cooking. it became known later when we were setting the table that we couldnt locate the bunch of bananas. we realized that throughout the day my 3yr old consumed almost all of them. she ate about 5 bananas. should i be concerned about a potassium overdose?
