Do stool for occult blood . Give syp.albendazole 200mg p/o stat

Hi I can fully understand your worry. Ease do not give Albendazole syp as suggested by other doctor.. as it can be given to babies above 9 months Incase you have started banana for baby in diet.... then those black thread are normal.. It would be better if you can do a direct consultation ( better online..due to this Covid)
