We actualley just had a talk on Asthma at the start ofthe school year to learn how to deal with kids having an asthma attack. I am pretty sure that the lady told us during this talk that babies are not born with asthma, t is something that develops over time as they are exposed to irratants. Im not 100% sure on it all, as it was the first day of term and a 8:30am talk- but I am pretty sure she said something along those lines. As for the predisposition of children who have family member who are asthmatic I am not quite sure the chance of them developing it.
