formula milk kitne time Tak use karna hota hai.? kya formula milk ko garam kar sakte hai?

A. See within six minutes of preparation you can use it and you can heat it again by keeping it into a pot where you have had hot water into it it’s like double boiling kind of a thing so you can bring it little warmer than room temperature that way mostly you should not do it and you should instantly prepare formula when you are giving it for drinking
