For your 8 kg baby, the usual Crocin (Paracetamol 100 mg/5 mL) dose is 10–15 mg per kg of body weight, which equals 80–120 mg per dose. This corresponds to about 4–6 mL of syrup per dose. Do not give more than 4 doses in 24 hours, and always use the measuring device provided with the medicine. Monitor your child after vaccination, and consult your paediatrician to confirm the exact dose and ensure it is appropriate for your baby’s condition.

The dose of Crocin drops for a 3-year-old child depends on the child's exact weight and the strength of the drops. Giving a fixed 5 ml may not always be correct for every child. The dose should match the weight-based recommendation on the label. To avoid underdose or overdose, consult your doctor before giving it.

For a 2-month-old baby, it is very important to be careful with medicines. Crocin (paracetamol) can be used for fever, but only in the correct infant dose based on weight, and Lanol should be used only if recommended by a doctor. Always check with your paediatrician before giving any medicine, and monitor the baby closely for any other symptoms.
