Baby bottle nipple also has a shelf life. Milk bottles and pacifiers are gradually worn out under the effects of high-temperature disinfection, cleaning, air oxidation, etc. Some materials may release harmful substances after being used for too long. When you find that the bottle and nipple are yellowed, not cleaned, transparent, or damaged, they should be replaced. Generally, the baby bottle can be replaced every 3-4 months, and the nipple can be replaced every 1-2 months. The glass baby bottle can be replaced as the baby's food intake increases, or when it is damaged.
Except that the baby bottle does not need to be absolutely clean, it is also best not to have these "clean-loving" behaviors:
① Like to use disinfectant wipes to wipe hands and toys for babies;
②Wash your hands every time you hold your baby, and do not allow others to touch the baby;
③The baby is not allowed to crawl;
⑤ Air purifiers are used in baby rooms all year round.
If you find that your baby’s immune system is not good, you will catch a cold and get sick as soon as you go out, and see if you are too clean and protect your baby too well. To be "dirty" appropriately is a kind of exercise for the baby's immunity, and bringing a baby becomes easier and simpler.
