Baby formula

Today is the 14th feb bought the milk the 12th of Feb My aunty who is looking after my daughter makes the bottles like normal swirls and she drinks started to see her throwing up

I made her a bottle saw the milk spilt in the bottle water and formula can literally be seen spilt in the bottle almost like the milk was old or sour milk Daughter was not feeling well and throwing up and having discomfort because of the upset stomach from drinking this specific formula from this tin never had a problem with it before because it is her regular brand of formula
