You may have to run more after a toddler. Till they are 8 weight gain/ loss is a natural phenomenon. Don't stress just check if overall you feel good/ weak. You may need to take you multivitamins, food accordingly. If you are nursing then there is little chance of gaining weight

Hi Smita, if you are underweight, it is still important that - you eat a well balanced diet consisting of seasonal fresh vegetables and fruits, nuts, eggs, cheese, peanut butter, lentils, pulses - you should eat five to six meals - increase your portion size slowly eg if you eat 2 rotis eat a 3rd one. - don't skip any meals - avoid junk food - Exercise regularly - Being Stress free is important. Practice breathing and meditation for relaxation. - Sleep well.
