Babies don’t have the immune system we adults have, therefore we need to sterilise baby bottles (I actually had to research why we needed one of these ’cause I thought they were a gimmick!) There are lots of baby bottle sterilizers on Gumtree and Ebay and the best thing about them is many of them are in “as new condition” and they sterilize- meaning when they do their job they make everything inside completely germ free! No second hand germs in sight! Have a look and see what you find! Just type baby bottle steriliser into the “find” function (Preferably an electric one, not a microwave one)
