Breast feeding baby no2.

Hi mummies. I'm officially expecting baby 2!!! I'm concern about breast feeding her once she's born, still a very long way to go but the thing is. I breast fed my first daughter and after I stopped my breast is barely even here, looks like two xiao long baos LOLS. ya so I'm concern if I bf baby no2 will my boobies be completely flat?? I'm so worried bc since young I've been very insecure about my breast still am though.
