Hi,
It doesn't matter if it is a vaginal delivery or one by c-section. In both cases the baby's head will have gone through some deformation. Baby cranio-sacral treatment which is very gentle can help a great deal. Good luck with a remedy choice. One of the most common ones is Cham, and Colocynthis as well. Both of those worked for my daughter when she had colic. The mother might want to check her diet too. I went off dairy products and gassy foods until the colic stopped.
