Yeah they do still get sick but my experience has been that it's never as severe or as long.

We've had a few bouts of colds throughout winter where DH, DD and I have all been miserable, snotty coughing messes...DS gets a slight runny nose for a day or two and that's it.

He's 11 months old now and he's had probably 3 snotty noses and that's all - by the time she was his age DD (who was FF'd from about 2 months) had numerous really bad colds, rotavirus, a UTI and a viral infection that gave her mouth ulcers. DS's managed to avoid all that so far...touch wood!!
