Generally speaking, baby's milk powder is in stages. According to the monthly age, 0-June is one stage, 6-1February is two stages, and 12-36 months is three stages.

Choose milk powder from the following aspects:

1. Choose infant milk powder owned by big brands and milk powder enterprises with national certification or even international certification.

2. Milk powder rich in DHA (docosahexaenoic acid) and ARA (arachidonic acid) can promote the development of baby's brain and eyes.

3. The nutrients in formula milk powder are not as high as possible. Only milk powder closer to the proportion of breast milk is more conducive to the establishment and functional maturity of the baby's gastrointestinal healthy microecological environment.

4. For babies with weak stomach and poor digestion and absorption ability, it is suitable to choose milk powder with moderate hydrolyzed protein formula, which is easier to digest. β -casein in ordinary milk powder is usually A 1 type, which will lead to "lactose intolerance" and lead to diarrhea, gastrointestinal discomfort and other symptoms, while A2-β- casein milk powder will obviously improve this symptom.
