Mine had delays, and it was frankly so long ago I could not begin to tell you, but I wanted to put something out there for you, becuase is can be very damaging to a youngster with a delay if Moms beleive that girls and boys have different milestone expectations. They have identical expectaions for all these milestones, and though many moms beleive that there is a difference, I want to restate it, just so no mother ever waits on getting an evaluation that her child may need becase she mistakenly thinks that boys develop more slowly. They don't in the normative standards.
Never wait on development, if you get an evaluation you don't need, it is far better than not getting one that you do.
