1, glass bottle: Glass bottle has the advantages of high safety, heat resistance, easy cleaning and moderate price, but it also has disadvantages such as fragility. For infants under 3 months, it is generally recommended to use a glass bottle. Because infants have weak resistance, bottles need to be cleaned and disinfected frequently. Compared with other materials, the glass bottle has better heat resistance, can be thermally sterilized and is easier to clean.

2. Plastic baby bottles: At present, there are three kinds of plastic baby bottles on the market, namely PP (polypropylene), PPSU (polyphenylene sulfone) and PES (polyether sulfone resin). Among them, PP (polypropylene) has the best performance, and has the advantages of high safety, easy cleaning, durability and portability, but it also has the disadvantage of relatively poor heat resistance. Usually suitable for children over half a year old, easy to hold.

3, stainless steel bottle: stainless steel bottle has the advantages of anti-falling, long life and low cost, but the disadvantage is that most of them are opaque and the temperature is not easy to directly perceive. Therefore, stainless steel bottles are suitable for babies over one year old.

4. Silicone bottle: Silicone bottle has the advantages of safety, light weight, softness and quick use, and is suitable for babies of all ages. But when buying, you should choose a big brand bottle with quality assurance.
