dear son got his very 1st fever when he was 3mth old due to the jabs and he got very bad flu n cough too, dont know the flu n cough got link with the jabs anot. and for the subsequents jabs, pediatrician advised us to give him the fever medi right after the jab to prevent him having fever.
but i suggest you dont give Louis the fever medi right after the jab UNLESS he has a fever. if he has fever this time then maybe you can consider giving him the fever medi right after jab for the next few jabs..
as for crankiness, dear son still okay, though cranky at times but he can still play.. except for the last jab, he was slightly abit crankier then the 1st two..
dear son took around 3-4 days for the fever to fully subside, for that few days, keep up n down.. as for crankiness, also about 2-4 days.. diffe babies have diffe 'pattern'
