Toddler or Toddeler?
Toddler
Exemple : ‘’My daughter is a toddler.’’
The noun "toddler", used to desribe a young child at around the age when they learn to walk, is often misspelt due to the pronounciation which can make it sound as though there is an extra "e" in it. The word derives from the word "toddle" plus the suffix "er" and so literally means "one who walks unsteadily."
