My baby was born at 5Kilos. Is she underweight?

I guess you mean 5 pounds instead of 5 Kg. 5 pounds = 2kg. 2kg is quite a small size baby if your baby has reached full term (40weeks). If your baby is premature (born before 36 weeks), the weight is considered quite good already. There are many positive steps you can take to improve your baby’s chances for a healthy start: -Breastfeeding your baby is one of the best things you can do to help her grow up to be healthy. Do not feed her anything but breastmilk for the first six months of her life, not even water. -Make sure your baby has all her growth and development check-ups. This will help you and your doctor catch problems at an early stage if there are any. -Once she turns six months old and you introduce her to solid foods, a nutritious diet can help your baby to catch up on her growth. http://www.babycenter.in/a1015212/your-low-birth-weight-baby#ixzz43Xnt1UWH
