hi. certain issues have risen with me and my family meaning that maybe going back to work as early as march is being discussed between me and my manager. the thing is i have always had trouble with my milk supplyas i had a lumpectomy which has caused problem and i feel i wouldn't be able to express enough milk as i only have a fridge so i cant freeze milk. if i do decide to go back in march, would it hurt to put my baby on formula. she will be five months in march.
