My first-born did everything early.......fast forward 12 years and I have another baby. Our little Sammy is a latebloomer. He was 6 weeks early so I gave him a two month leeway on everything but he has consistently been 3-4 months behind on everything.
We took him to the neurologist in our pediatrician's clinic and they told us that he was just on his own time-table and had nothing wrong with him. They were right! When this kid makes up his mind to do it, he practices for a couple of days and then masters it.......but not a minute sooner.
He sat at 10 months. Did not pull up til 12 months and did not walk well until 16 months. He can say words and surprises us with one every now and then, and understands everything said to him, but will not converse til he is good and ready. He is 22 months and we go back to the neurologist at our 2 year wellness visit.
So don't feel alone and don't worry too much. Some kids are just really laid back and in no hurry to meet those milestones. Just keep working with the baby but don't wear yourself out......they DO have minds of their own.

If you get too concerned, just ask your pediatrician to recommend someone.
