I had a bad chest infection and tonsilitis when DD was about 12 weeks. I was a mess - it was truely horrible. DD didn't even get one sniffle, I was so amazed. I was told to expect her to get a few mild cold like symptoms, but that is generally it. I think there is some benefits from them being exposed to you being sick, like thier immune system being exposed to it as such. I hope you get over your cold soon, its so hard taking care of yourself and bubby when you are crook.
DD is 3yr 8 months - DS is 6 months
