I have been putting little ones bottles and breast pump etc in the dishwasher since he was 6 weeks old. I had read at the time that the DW would sterilise the things completely. just to be safe though after theyve been in the DW i sterilise them in the steam steriliser thinger. friend said the other day though that she had heard that the DW isnt suitable until they are 1 because of the detergent. has anyone else heard this? Little boy is still only 5 months so am bit worried now.
