Hi momshies! I was worried lng po kasi di pa ako dinadatnan since i gave birth but im a bf mom until now. Because in my first born i already had my mens when he is 1 yr old and also i breastfed him din while in my second child Its been more than 1yr na ksi aq wla pang mens so i guess if some po could help me or have this kind situation din po thank for response.
