My daughter is 2 years old last February 1st and she is weighing 19 pounds and 31 inches tall. I know she is under weight and short for ideal. I am 5'2 height and my husband is 5'6. I am wondering if there's any vitamins to improve her appetite and I think b12 to make taller. But is there anything you can recommend us to do and she needs to take. Thank you in advance. Hope you can help me. How will I know or where can I see the reply / answers
