My breastfeeding wife looks like she's having colds. How can we prevent our baby from getting colds too?

You don't have to worry about baby getting sick. When the breastfeeding mommy is sick, the mommy's body will produce antibodies to fight the cold viral. With that antibodies, it is that passed on to baby by breastmilk, it's also helping the baby immune system to build up a defense from the viral. Always remember to wash hands or even wear a mask if you are still a little concern on passing the virus to baby. Mummy can drink more water and vitamin C to strengthen her own immunity
