Do I really have to sterilize bottles and nipples?

You should sterilize your baby's bottles and nipples daily, if possible, to reduce the risk of infection.

For the first several months of your infant’s life, your baby is particularly vulnerable to viruses and bacteria that can live and grow on normal surfaces. It is a good idea to sterilize bottles and nipples at the end of each day in order to have a clean supply on hand when you need them. There are tons of commercially available sterilizers out there that can be used relatively quickly in the microwave. Just read their directions carefully to know how to use them.

  1. With my first baby I sterilized everything using the Born Free microwave sterilizer. It works great! However, when my second baby came along, taking care of 2 children under the age of two can be exhausting. I decided to simply put the bottles on the top rack of the dishwasher. I have a setting for added heat and I use an all natural, free and clear detergent. Sterilize if you have time, but I totally think dishwashers are so powerful these days that they are just as good. I feel like I enjoyed the “newborn” stage more with my second child because I didn’t let myself get overwhelmed and simply did what worked best for me and my family.

  2. All I do for my baby’s bottles is boil them when I open them and then wash them after each use and he’s doing fine. I’ve never heard of any kind of microwave sterilizing just boiling in water for a few minutes.

  3. Great question! This is something I definitely did not know as a first time mom. Microwave sterilizing bags are awesome.
