Hi, I'm getting my t-shirt order ready on jiffyshirts.com, and I love the look of the toddler ringer tees by Rabbit Skins. The reviews said they run small, so I'm trying to figure out what sizes to get. My boys currently wear a 2T and 4T in shirts from stores like Children's Place, Gymboree, and Carters. Should I go with that, or get the next size bigger? My ODS can usually wear a 5T in the brands mentioned above without swimming in it, but YDS would be drowning in a 3T from those places. I would love to hear from anyone who has used this brand in the past with regards to how small they really ran. Thanks!
