    Hi there! I’m on my 36 pregnancy week, and recently, my husband got us some baby stuff, including the baby bottle. I’ve already read a lot about sterilizing and care, yet I still wonder about one thing, and I hope you’ll explain it to me. Is it necessary to sterilize baby bottles every time I use them, or I can just wash them?

    • Hello! I think it’s a matter of your personal choice. As for me, I sterilize the bottles for my baby once a week. My pediatrician says that the child should grow up in vivo, and not get used to sterility from birth. What should you do? There’s no one correct answer to this question. Each mother should choose the best tactics for herself and her baby.
