What is the knowledge of caring for a three-month-old baby?

A three-month-old baby will encounter many problems. For example, the baby is prone to some digestive system diseases, and often has some skin problems. In addition, he is prone to colds, high fevers and other symptoms. In order to avoid these situations, parents need to take good care of the baby in all aspects, such as feeding correctly, keeping warm, taking good care of the skin, etc.

Three-month-old baby care knowledge:

First of all, everyone should know that babies usually start to add complementary foods after 4 months. Therefore, for three-month-old babies, the timing of adding complementary foods should be in line with their physiological characteristics. Adding complementary foods that are not suitable for digestion too early will cause digestive disorders in babies. Adding complementary foods too late will cause nutritional deficiencies in babies and is not conducive to cultivating the baby's ability to eat solid food. Moreover, the varieties of food added should be increased from one to multiple. Try one complementary food first. After 3 days to 1 week, if the baby does not have indigestion or allergic reaction, then add the second complementary food. The amount added should be increased from a small amount to a large amount, and the amount should be gradually increased after the baby tolerates the food to avoid causing digestive dysfunction.

Secondly, the food should be prepared delicately, starting with liquid food, gradually transitioning to semi-liquid food, and then to solid food, to allow the baby to have an adaptation process. In addition, the best time to add complementary foods is before breastfeeding, when the baby is hungry and can easily accept new foods. When the weather is too hot or the baby is unwell, you should postpone adding new complementary foods to avoid causing digestive dysfunction.

In addition, parents should gradually extend the time their baby takes an outdoor air bath, from 5 minutes each time to 20 minutes each time. If babies have appropriate activities in the sun, it can improve their physical fitness and benefit bone growth. After the baby gradually adapts to outdoor air bathing, he can start sunbathing in the third month. Sunbathing not only has the same effect as outdoor air bathing, but also promotes blood circulation, strengthens bones and teeth, increases appetite and promotes sleep.

Good habits for babies must be developed through cultivation and training. The baby's urination habit training should start 3 months after birth. Before going to bed, after waking up, before and after breastfeeding, before going out, and after returning home can be set as fixed times for urination training.
