We've never sterilised toys.
We stopped sterilising bottles when LO turned 4 months old. I know it's not the guideline time, but in my sig you can see that I'm not the type that follows them anyway.
My reasoning is that we haven't sterilised her dummies since she was about a month old (we kept getting sterilising solution IN the teats, and I hated the idea that she was sucking it into her body), and she will keep the same dummy for a whole day, and if it's dropped, we lick and stick it back in her mouth, so she's been getting our germs, and germs from the surfaces too. If it falls on the ground/floor, we will get another dummy, but anywhere else, and it's given back to her.
She also sticks her hands and feet in her mouth, which obviously you can't sterilise, and we have never sterilised her toys. We buy them from the shop, and they're given straight to her, and she puts them straight in her mouth. Didn't seem much point in continuing to sterilise bottles, especially since we also make up her milk with boiled water at room temperature.
I would also add that my LO has never been ill because of not sterilising. She has only had one cold, and that was caught from me (I know, because I showed symptoms 3 or 4 days before she did). And I know people will argue that she can ingest germs etc, but surely she will get germs from picking things up once she's crawling, and sucking on her hands. As far as I'm aware the danger in milk is if you give it to them after 2 hours' sitting out, but not that it's not sterile. The milk has been packed in a clean environment, and therefore it's not dirty, it's just not sterile, but then neither is my house
