My 1 year old was born 1 month premature, stayed in the NICU 1 month, and literally has been sick over 70% of his life with either rev, other respiratory symptoms symptoms, or the flu. Could he have a condition with low immunity? He is also failing to thrive and can t get over 15 lbs even though he is now 14 mos old. What would you test for?
Hi, Premature babies have low immunity and also current weight is less, so he will be more prone to get easy infections.  You should do full blood count to see the basic blood parameters at the moment.  If any parameter like WBC or Hemoglobin is less than after advise proceed in that direction to rule out any cause. But in general keep tight hygienic condition for you baby. Good luck and wishing him healthy life! Hope I have answered your query. Let me know if I can assist you further.
