Can I use my breast as pacifier? Whenever baby is inconsolably crying, I will resort to giving her my breast to pacify her. I am afraid this might overfeed her as she has few episodes of bringing up milk.

For me,it is ok to do that. It makes my child very happy, not fussy and quickly calm down after i nurse her. Also this phase will gradually reduce when yout baby starts exploring and crawling and slowly let go of you. Of coursw she'll keep coming back to you when she's tired or upset, but she'll trust you so much.
