How many is too many?

Anna

My dd is turning 4m on Feb 17th. She has another cold. Some background, she was born with mucus in her throat and lungs and had to be suctioned and then she coughed it up for a week afterwards. When she was 10 days old my 6yo son brought a cold home from school and she got sick. At 5w3d old she was admitted to the hospital with meningitis, at 9w old she got another cold which was the worst one cuz she lost her voice and would cry cuz it hurt and it hurt when she cried so she'd cry more and she was throwing up with it too and it was a miserable 8 days (thankfully they aren't lasting long) and now at roughly 15w old she has another cold that kept me and her up half the night on the couch cuz she couldnt sleep. So far the only way she can sleep is if she's in bed with me and dh. We've tried everything else. We're all on multivitamins, she's on the one with vit a/d/c in it.

What else is there to do? When we were discharged from the hospital they told me to be aware of how many times she's sick because her immune system could have been compromised.
