My DD is a year old and for the past week we've moved from formula to cows milk.
I know sterilising is a matter of opinion and effectively we could've stopped sterilising at 6 months but we chose to carry on due to potential harmful bacteria in the formula.
Now she is one I believe it is more "okay" to stop but why at 1?
What do the rest of you do?
I don't mind continuing to sterilise but is it necessary?
