worried all the time

Last night I only sleep for three hours I was always awake I could not shut off my mind. I was worried about my daughter Izabel’s coughing. Every few hours she woke up coughing and crying. I keep checking on her to make sure that she was ok. At 5:30 am she woke up again crying and coughing and after a few minutes she threw up on me, when she calmed down she went back to sleep. I thought that we would take her to the doctor this morning but I never wake her up she was sound asleep. Now I think she looks ok I never hear her coughing. I am worried all the time when one of my babies gets sick.
