回复：3 years boy sick very frequently

My son was similar at the earlier stage of daycare. He began to daycare at 2yrs9mons, and from 3 yrs old, he began to be sick one time per month, till he was 3 yrs 6month..then back to normal..

During that 6 months, I lost weight 10pounds.

I thought possibly it was because of virus environment he couldn't be used of.. and after 6mons, he can be anti-virus better...

Now he is very good, possibly one time sickness per 6 months...But who knows... now he is 4yrs old and 3mons..
