I have two children, one is 4 and the other is 9 months. The 4 year old is always ill, infections, bugs, pneumonia, and temperatures. It's quite rare for us to get through 1-2 weeks without something. My youngest is exposed to it all, but seems much more hardy. We've been told to have an immunological assessment. I know getting ill, especially in young children is common, but I'm interested if it's like this for everyone? Or if it was, what age do they grow out of it? Thank you!
