When it comes to giving vitamins for babies, there are two schools of thought at practice here. Depending on your doctor, he will either tell you that your baby does not need vitamins for growth if you have a newborn child. Other physicians would recommend giving your infant vitamins for children in the form of multivitamins. It is up to the parent which advice to follow although it is always best to listen to your doctor.
A newborn baby is deemed healthy enough if there are no complications during childbirth. This is the reason why other doctors do not give childrens vitamins just yet. This is especially true for breastfed babies because all the nutrients they need in their early life are found in the mother’s milk. When the baby starts to quit drinking milk and move on to solid foods, this is the time that doctors usually require vitamin for kids.
It is difficult to say whether or not a child is getting enough nutrients when he is eating solid foods. The child can eat healthy one day and the next day he might spit up all his food. He might like some fruits but he might not like most of the veggies you will introduce to his diet, which have the essential vitamins for kids.
For infants, vitamins in the form of liquids are suitable. Stay away from tablets and gummy vitamins for the meantime until your child is 3 to 4 years old. Vitamins for toddlers and vitamins for teenagers are basically the same. Both needs Vitamin D and Vitamin C. You can get Vitamin D from sunlight and Vitamin C is present in foods such as oranges and limes.
If you live in a place where sunlight is rare or if you do not get sufficient amount of Vitamin C in your diet, you will need to intake vitamin supplements. The supplements for children are normally in liquid form so kids can take it orally without so much of a fuss. Consult your doctor about the supplements before you purchase one.
