Twenty-seven months sits right in the middle of the period between the standard 2-year and 3-year developmental checks and a surprising amount is happening. Your toddler is not the same child they were three months ago. Language is probably the most dramatic area of change at 27 months. Most toddlers at this age are using sentences of 3 to 4 words regularly and some are producing much longer sentences. They are asking questions constantly, particularly what and where and who. They are beginning to use pronouns like I and me, though they may mix them up: me want that or I did it. Vocabulary is typically 200 words or more and growing daily. Physically, 27-month-olds are noticeably more coordinated than they were at 2. Running is smooth. Jumping with both feet is well established. Many toddlers at this age are starting to balance briefly on one foot, beginning to pedal a tricycle or balance bike, and walking up and down stairs with increasing confidence. Fine motor skills at 27 months include drawing horizontal and vertical lines, beginning to draw circles, managing large zips with assistance, using spoon and fork with reasonable accuracy, and turning pages of a book one at a time. Emotionally, 27 months is still firmly in the toddler big feelings era. Regulation is developing but far from complete. Tantrums continue. What you may notice is a slight increase in the ability to be reasoned with and a genuine interest in doing things correctly according to rules. This rule awareness can work in your favour during challenging moments. Talk to your pediatrician if your 27-month-old has fewer than 50 words, is not combining words into phrases, or has lost skills they previously had.
