once he starts feeling better breathing well and not coughing as much he can do most any activities. if he becomes too tired or overly stressed then back off a notch. perhaps i would have him hold off on sports participation like soccer until he has fully recovered but he can do most normal activities including going to school if his medical provider gives the "okay". there are varying degrees of pneumonia and some are quite mild. he does not have to remain in bed or in the house but remind him that rest is important to his recovery time.
my son is 7 and has walking pneumonia. is some activity ok or should he just lay low? about how long?
