Hi Pinar,
Congratulations on the birth of your son!!
It's ok to be scared....this IS a scary thing especially if you were not prepared at all for it. Take the NICU journey one day at a time. It is a roller coaster of sorts, but you can do it. My daughter was born at 28 weeks just over 2 years ago weighting 2 pounds, 10 ounces. She was tiny.
I normally write a longer welcome, but tonight I am exhausted and need to go to bed. I will write more to you later.
Know that you can always come to this board to ask questions, vent, yell, scream, rejoice....whatever. We know exactly what your going through.
