My 19-month-old son grinds his teeth and does not eat properly. Should I give him Albendazole?

Hi doctor,

My son is 19 months old. He is grinding his teeth most of the time. He is not eating well and takes only one spoon. After that, he has a feeling of vomiting. I am giving food with a long interval between every bite. I am giving him only mashed foods. Previously, he was taking two idlis and now he is facing difficulty in taking half idli (rice cake). One of my friends suggested me to give Albendazole syrup as his symptoms suggest worm infestation. Can I give Albendazole syrup? If yes, then please mention its dosage. Previously, he was in the weight of nine kilograms before two months and I have not checked his weight recently. I am worried about his eating habits. He became thin when comparing to before. What to do?
