The Stokke Clikk high chair is intended for ages 6 months to 3 years. As with most high chairs, infants should be able to sit on their own before using the Clikk high chair.   However, that 3-year limit may be a little optimistic. The maximum weight limit of this chair is 33 pounds. While the average 3-year-old weighs 31 pounds, that does mean some 3-year-olds are weighing in at higher weights.  There is another option that Stokke has come out with called the [easyazon_link identifier="B07B68CCSX" locale="US" tag="experiencedmommy-20"]Stokke Steps Chair[/easyazon_link] if you are interested in a chair rather than a booster seat for a toddler or older child.  This seat supports up to 187 lbs making it work far beyond toddler years for your child.  You also can add accessories to this chair to make it a baby bouncer for an infant or a high chair for an older child.
