Do you think I should be talking to an attorney in regards to my Newborn Son's care at the Hospital?

My Son is 2 months old. From the moment my Son was born I saw a sacral dimple on my Son's spine and his left foot is slightly deformed (hip Dysplasia). When I was at the hospital I asked the on call Pediatrician about it and he said my Son looked fine. As weeks went on it bothered me and I made our regular pediatrician aware of my discovery. Our Ped was very concerned about both conditions. We're now being sent to a nuerologist and a Ped orthopedic Doc. Would I have a case against the Dr. that was at the Hospital I gave birth at? Now looking back the Ped at the Hospital kind of blew me off. I feel like my Son was not properly examined. Thank you
