Let me share my experience with my second baby,I had to to resume back to work after three months of maternity then my baby refused to take a bottle milk,guess what?when I observed that I had just a weekend to spend with her at home before resumption I placed her on breast milk hunger Strick whenever she's starts to cry I will take her outside the house sing for her and bring her back to feed her with the bottle,she refused then after about 30 min to 1 hour my baby sucked all the bottle food.
