Not feeling the love ...

I am not loving my new pediatrician right now. We need to get Jacob into a developmental pediatrician. We can't get into one without a referral from our primary ped. Our primary ped would not refer until he saw the IEP. We sent him the IEP last week, we confirmed he received and still no call back. I called and said we really, really need the referral so we can proceed. Still no call. I am not sure what the acceptable time frame for waiting would be. Is this where I need to be the squeaky wheel that continually calls? Argh.
