My little boys are 23 months apart. Adrian is almost 1 and Fritz is almost 3. Fritz wore 2T clothes last summer. Because he has barely grown since 18 months, he is still in 2T this year. Adrian is in 18 month clothes and is starting to outgrow some of them and moving into the same size 2T clothes as Fritz. How long until little brother overtakes big brother? Or, I wonder if Adrian will follow the grow a lot until 18 months and then practically stop pattern, too.
