Fussy with a cold
At 8 months, especially during the winter time, it is common for infants to be getting upper respiratory infections.
They have lost all the immunity they got from you through the placenta
and have to develop their own immunity by getting infections. As long as there eating well
, you don't have to do much for a cold. Just suck out the excess mucous. If the child remains fussy, have her ears checked.
