My MIL never sterilized my husband's or his sister's - just washed well and rinsed with boiled water. When we took DS to visit last Sept (Lithuania) when he was 3 months old she thought it was odd we were still sterilizing (I insisted and, credit to her, she would sterilize them for us).
Her daughter, my dh's sister, is expecting a baby and it came up in conversation with MIL that they won't be sterilizing baby's bottles.
I'm curious if anyone on here doesn't bother to sterilize a newborn's bottles and your experiences. At the moment I believe it's far too risky and not a risk worth taking.
