Cold and flu

[Shubham]

My 5-year-old is always having a cold and he feels cool than anyone else. Accordingly, I usually have him wear a sweater even on warm days. He also catches a cold easily which then leads to asthma and often whatever virus is around. Wonder if there is an underlying condition? Thanks

The underlying condition could be nutritional and vitamin deficiencies even if he is eating well.
Has he had vitamin D and full blood testing done?

Has he had issues with sinus or ear infections?

Your child might have allergies as well...I highly recommend you request a referral to an allergist so he can be fully tested for allergies and asthma.
