It is said that the germs that can grow out of milk is particularly nasty and therefore bottles should be sterilised for as long as they are used... And then my friend said, but the bowls and soups have milk touching it too so why not sterilise them also? And I did not know how to answer....
By the way, my LO doesn't look like she will be crawling soon although everything in her hands do go into her mouth!!!!
Maybe rinsing in hot water is a good option too, thanks!!!
