When is everyone thinking about stopping sterilising bottles? With my daughter I carried on until she was about 14 months old because she got a viral infection at about 12 months so I was worried about risking making her ill again. I know the guidelines are 12 months but we are going on holiday when my son will be nearly 11 months and I don't really want the hassle of taking a steriliser along with all the other stuff we need, but I don't want to stop too early either ?
