hi... my 54 days baby passing poop with muscus I gave cold medicine for past 10days. today she vomits 3 to 4 time spit up many times like curdy after she vomits she start crying for milk is this normal I attached the image also

A. in the picture it is basically loose motion which could be infection so loose motion may be because of either some infection there could be loss of water and electrolytes so a proper hydration is required give ORS and also give probiotic like enterogermina two times 3 day
