I have a 2 week old baby that has been bottle raised since day2. She has been taking the bottle fine until yesterday she took only half what she normally has in a day. The other change has been her poop has been a better consistency but has a bad odor. I'll get a stool sample tested tomorrow but until then should I let her eat only what she wants or should I try to drench her the rest? She was taking 16-18oz a day?
