Evening all My baby is nearly 4 weeks and unknownigly today she was in the presence of another toddler who had chicken pox. Since my lo has been exposed to the toddler my worries have set in about my lo catching it. My lo is breastfed but I am still deeply distressed. Those who had babies that have already had chicken pox how quickly did the symptoms appear after exposure? If your child was breastfed,was he/she not affected?
