Uk momma question

Are you going to keep sterilising the bottles until 12 months. Personal I can’t really see the point. I have never sterilised her dummy and don’t intend to do her bowl and spoon either. She puts EVERYTHING in her mouth none of which sterile. As we are told to make the bottles up as we go along there is hardly any opportunity for bacteria to grow anyway?!? I know it doesn’t take long and if someone had an answer to keep doing I will. I just think trying to keep all germs from baby isn’t actually doing them any good??
