A. neck holding of the child should be present by 4 months to maximum 5 months of age. regular massage of the xback as well as the neck will help in strengthening the muscles of this area. if neck holding and head holding is not proper by the end of 5 months it is important to meet the doctor for examinaxtion to find the cause of delayed milestones
