I know I'm a little late providing info, but I read your question and just had to pipe up.
My son had surgery at just a few weeks old for Pyloric Stenosis and was in the hospital for a few days (Children's Hospital Mpls., which I LOVED). After his surgery he got a cold, which we thought was no big deal, but it kept getting worse. The cough woke him up at night, and none of us could sleep. One day he started coughing and his mouth turned blue and he couldn't breathe. We rushed him to the ER, and as soon as Dr. Mila Santiago (also LOVE) looked at him and heard his cough, she said "Whooping Cough. He has Pertussis." The quick-test came back negative, but within an hour the long-culture came back positive for Pertussis. We had to call and cancel his 8-week check up for the next day, where he would've gotten the vaccine, because he already had the condition. He was in the hospital for a few days where he was monitored 24/7 and hooked up to a monitor at night to make sure he didn't stop breathing, which he did, once - thank goodness we were at the hospital at the time - and he had to be on IVs and couldn't eat regularly because he'd cough so hard he'd vomit or gag. My baby was just two months old, already through surgery, and was hooked up to all these machines and could've died, all because someone didn't get vaccinated and spread this disease to other people - innocent people, like babies who were scheduled to be vaccinated and just hadn't gotten to the appointment yet.
My husband and I, my parents, grandmother, and my in-laws all had to go on antibiotics, my husband, my mother, and I all missed a week of work, and my mother-in-law and my grandmother actually came down with Pertussis themselves.
My son missed out on his 2-month vaccinations and was off schedule for the rest of them. The hospital is required to report any cases of communicable disease to the department of health, so we had to communicate with them on my son's condition and made a trip down to their office so that they could take some records on our experience.
As a mother of children who have been vaccinated, I think it is appalling that people refuse to vaccinate their children. I've actually heard of people who don't just because their child got fussy or a little feverish once, and they didn't want the hassle. This is ridiculous. If you're not going to think of your own child's health, think of the risk you're posing to other children by subjecting them to whatever your child might carry, even if he/she doesn't get the disease him/herself. Our pediatrician refuses to see children of parents who refuse vaccination, on the very principle that she's seen what these diseases do to children, and it breaks her heart.
I know there are many people out there who would dispute me, but I don't think they'd feel the same if they'd seen their baby hooked up to those monitors and tubes and come so close to dying from something they themselves cannot control. We must protect our children and choose for them when they are too young to choose for themselves. I felt so helpless, even though I couldn't have done anything differently to make it turn out better. I wouldn't wish that on anyone.
I hope my experience has enlightened you, and I'm certain you'll do what's best for your baby girl.
