As listed by Medline Plus, the average resting heart rate for toddlers between the ages of 1 and 2 ranges from 80 to 130 beats per minute. About.com Pediatrics further explains that this rate is dependent on factors such as the toddler's activity level.
Medical News Today shows that a child's resting heart rate changes as they age, and will also develop healthy variations depending on their environment and other factors. Toddlers who have been playing, have anxiety, or have just stood up may temporarily have a much faster resting heart rate.
Medline Plus recommends that any toddler with a resting heart rate that is continually above or below the averages should be seen by a qualified pediatrician to check for any underlying medical conditions.
