suggest some particular medicine

This is a serious chest infection in a two month old kid, and the weakness with falling down means it needs a vet review today. I cannot name a particular medicine for you here, because the wrong antibiotic or dose can harm a young kid. Keep it warm, dry, and away from cold wind and dust. Give clean water with oral rehydration salts if it is weak, and offer milk or soft feed in small amounts. Do not force-feed. Since it is still not active after treatment, this has been going on for multiple days without improvement — a veterinarian must see this animal today. If breathing gets faster, the nose starts dripping more, or it stops standing, take it for urgent examination at once. Consult a veterinarian before administering any medicine or treatment.
