when I was pregnant I felt like I had a super immune system. I work in a school and I went the whole school year without being sick. I usually at least get a cold or two. I had my LO in July and I've had three colds that have knocked me down for at least a week. I just had a cold at Thanksgiving and now I'm sick again!! Is there anything I can do to boost my immune system? Does breastfeeding effect our immune systems? I'm sick of being sick!!
