Level 1: Basic principles of infant feeding There are some basic principles that need to be followed when feeding an infant. First of all, breast milk is the best food, and it is recommended to start breastfeeding as soon as possible after the baby is born. Secondly, babies need to eat frequently, at least 8-12 times a day. In addition, you need to pay attention to hygiene and safety when feeding to avoid cross-infection. Level 2: Breastfeeding skills Breastfeeding is the best choice, but it also requires mastering some skills. First, correct posture is very important. The mother should sit upright and hold the baby close to her chest. Secondly, the correct sucking method is also very important.
