y dont u reconsider your decision. u can give breast milk even if u r going to work. u can express your milk using breast pump and feed the baby with pallada. once u feed your baby in one breast the other breast becomes full. so u can v.well express it with breast pump. u can keep this milk in room temperature for 6hrs.u can keep it in refrigerator for 24 hrs. many working ladies now r doing this and so the baby also grows healthy. formula milk or any other milk for that matter is not good for the baby and at 3months of age when anything other than breastmilk is given the baby will get infection v.often which will be v.depressing for u and the baby will also suffer. but even if u express milk and give it should be given only in a pallada not through bottle. because this will cause nipple confusion and the baby wont know how to drink from u once u come back.many working women are feeding the babies for 2years. isnt that surprising? it will be difficult for u only for next 3months. once the baby becomes 6mon old, u can start weaning and u can reduce the number of times u feed the baby, even if your baby cries u can give other food to satisfy him/her. hope u reconsider ur decision. this will help your baby grow mentally and physically healthy and his/her performance in schools will also be good. mom's milk is good for brain growth. actually babies should not be fed even water till they r 6months old. only mom's milk should be given to them. do u know that feeding the babies also help the mothers to regain their figure and lose weight. not only that, it v.much reduces the risk of breast cancer. if u have any more doubts u can consult a good pediatrician and a good gynecologist. remember consult good ones. all the best!!!
