I am torn on what size winter jacket to buy for my 18 month old. She is on the taller and thinner side (currently 32.5 inches tall) so I kind of want to buy 2T, but I'm afraid her sleeves will be way too long this winter (but maybe we can reuse the jacket next winter too?) are longer sleeves that much of an issue? 24 month sized is 32.5-34.5 inches tall and 2T is 34-36 inches on the size chart.
