I would recommend our doc- Dr. Valerie Mokides in New Hyde Park. She is a DO and she is not opposed to non-vaxing. She will explain to you all the risks that in her view you are taking, but she will not pressure you or right upfront confront you. We are at 9 months and we have been delaying.
However, research whooping cough, there have been about 200 cases in LI and I would make sure I am familiar with this disease.
From where you live, you just hop on Grand Central for a few exits and you are there. If you have a car, she will be convenient for you. I live in Whitestone (northern part) and I drive to her. There is always parking. I was going to go to Manhattan, but I am glad I did not- for me it would have been so stressful to deal with crowds and parking while taking my newborn to the ped.
Valerie is all about nutrition generally. However, if she thinks there is a danger present, she won't hesitate to prescribe medicine.
Please feel free to IM me if you would like to ask me more questions about Valerie.
