Congrats on the kid.
Feel free to calm down. You sound like I did and still do at times. Then again, I have twins. Which I will say is different but they too were born premie and I know that what you are going through, is alright. You're doing awsome and don't really have anything to worry that much about, or so it looks to me.
If you would like help, feel free to message me. I'll be sure to let you know if I don't have the answer.
The BW of my smallest, Dain, was 2lb 12oz. Large one, Kori, 4lbs 6 oz. I may be new but I'm willing to do my best to help you out.
