My son has been falling sick every 2 weeks for 4mth after going to the CC. Thinking of change school

There's no need to change school, perhaps it might be kids immunity or environment in CC that may have cause your little one to fall sick easily. You might want to seek doctor advise and boost your little one immunity with Vitamins and if necessary vaccines like flu etc. Perhaps this may help. All the best mummy, don't stress yourself 😊
