I sized up when getting J snow pants this year so hopefully they fit him next year. He is in 2T but I bought 3T. The tag on the 3T snowpants say 28.5-32.5 lbs. He is 30 lbs at 33 months. I thought a 4 lb range seemed really small for a toddler - do toddlers/preschool age children gain less than 4 lbs in a year? I thought it was more.

At his 2 year well child check he was 26.6 lbs, at his last sick visit (end of October, so 32 months) he was 30.4 lbs. So definitely over 4 lbs a year for him.
