Why Can’t You Store Breast Milk In A Bottle With Nipple?

Many mothers get confused that storing breast milk in bottles is okay, but okay when stored directly in a bottle with a nipple attached. Well, here’re the two main reasons why you should avoid it.

1. Potential Sickness Threat

As mentioned earlier, the nipple is exposed to the atmosphere. Regardless of how you wash and dry it, there is a potential threat of bacterial growth at the tip of it.

When your baby sucks the milk, it will transfer into the blood system and harm their health.

2. Lack Of Container Lid

Most of the feeding bottles don’t have a container lid attached to them. So, without the tight lid, the milk will overflow. 

Apart from it, the nipples also have a tiny opening through which the air can pass, making it a suitable place for bacterial growth.

How To Warm Breast Milk From Freezer?

Many new mothers directly heat up the breastmilk in a pan; that is not the right way. Similarly, you can’t put it into a microwave oven even for 10 or 20 seconds. Here’s the right way:

You can also place the bottle directly under the hot running water if you need to feed the baby immediately.
