I have a one month baby whose going to be 2 months on 21st Dec....I hv been feeding him breast milk only but for the last two days he seems to be hungry n breadt milk seems not to be enough for him....so wat cn I feed him apart from my breast milk??? N next month onwards I hv to join work so jus feeding him breast milk seems difficult n not enough.....Please suggest me wat else cn I feed him and how much????
