Hello Doctor, My son is 10 months old. Today evening, he played very enthusiastically and crawled and we were playing hide and seek games. After that we made him to laugh by doing funny activities.. Just a few minutes after that, he seems to have fits (I dont know how to explain that.. His face seemed red for a few seconds and his body became stiff). Today only we are noticing this peculiar act. 3 times he behaved like this today. I am worried, He is sleeping now. What might be the reason for this? Is anything serious? Please help me.
