I have a 4 day old Newborn I want to know if a midwife for daily baby massage will be good as Doctors say it's not good and I shouldn't.

Lack things to do ? There is data from physical therapists that simple flexion/extension postural maneuvers and neck massage can reduce afternoon crying. That said, these are things moms can do with no outside help. I have heard of such "therapy" offered by a variety of non traditional sources but consider this a waste of time and money.
Not essential . infants do you like massage therapy. There is no reason you cannot do this at home. The infants outcome will be no differentwithout massage therapy.
Not harmful. Baby massages are not harmful if done correctly, data regarding benefits are scarce. However, if you have the resources, in my opinion, go for it.
