my baby was 11 months old and weight is 5.5is it normal or abnormal

A. Ma’am this is abnormal because a child should be somewhere around five or 6 kg by the age of 5 to 6 months or maybe seven months not more than that your child is extremely underweight which is abnormal plus it is unhealthy immediately should check with your Doctor No matter if the child is active also the weight is still very less
