I just gave dd a bottle feed while I was surfing on the computer and she took half then fell asleep. I carried on and then she woke up and started crying for more. I checked the time and it had been about 40 minutes so I gave her the rest thinking it would still be ok, because it was still under an hour later. Then ten minutes later it dawned on me that I'd definitely been surfing for longer than that (I thought the time was just going slowly) and I realised the PC clock was about an hour behind. So the milk was about an hour and three quarters old!
I feel like s**t for not realising before I fed her but how harmful is it? I just keep thinking that now she'll probably end up with some stomach bug or something because of me.
