My youngest dd is 8, turning 9 in about 6 wks. We just did a major declutter (as in last 3 weeks) & gave away the kitchen as she either cooks in the kitchen for real or uses the American Girl sized one (from Target or somewhere) for the dolls. Her toy kitchen got a lot of use past the age 2 1/2. My oldest ds played with the kitchen until 5ish. Middle 2 kids played w/ kitchen until 7/6ish. So, all of mine were different but all enjoyed the kitchen past the age of 2.
