Sim, I'm not one for having Oscar in a sterilised environment, either, as anyone would be able to see just walking into my house (or seeing me let him let loose in the garden or the lawn with leaves)! The formula is a different story, though. I don't sterilise my bottles when they have EBM in them because hot, soapy water will clean that up no worries. Formula is subject to spores and it's something you are putting into the baby's stomach, so, yes, you are taking a risk there. It's great that your kids never got anything, but I wouldn't recommend anyone stop sterilising if they are using formula, or to let the Use By date slip too much on a tin of formula, but Neeny's already indicated she won't anyway, so that's sorted
Anyway, off to the chemist now. Geez, I'm loving this weather - I love how Melbourne weather gives us a break before launching into hot weather again!
