<s>[INST] my baby is a very active 3mnth old girl who laughs a lot when she wakes up in morning.but today she was very dull she is not responding to my calls neither laughs or smiles and not responding to her favourite toy which she sees and laughs immediately seeing it.is this normal or something of concern [/INST] Hi, Did she sleep as usual last night? Anyone else in the family having fever or flu? If she does not have any other symptoms and is feeding well, we need not worry now. This may indicate a viral pro Chat Doctor.  In case she develops fever, give paracetamol. Take her to a doctor if she develops additional symptoms, is not taking feeds or vomiting repeatedly Hope I have answered your question. Let me know if I can assist you further.  </s>
