My first ds is 2 and a half and used one bottle a day from 6 months til one year. The bottles have been in the cupboard ever since. The teats look a bit manky so I have replaced them but is it ok to reuse the bottles for my new baby when the time comes do you think - sterilising as normal? Also what about beakers, cups, spoons etc for later - some of the manky ones I've chucked but some seem ok.
