ive had a blocked milk duct for nearly a week now which after a week of trying to sort out at home i finally went to the doctor yesterday and was prescribed a weeks course of antibiotics. although ive still being feeding off that breast, my breast never feels full and my 4 weeks old seems frustrated when latched on and im wondering if my milk is drying up. my other breast is fine but even after 30 mins of so on that breast my son never seems full. i offer both breasts at each feed. however, since ive had the blocked milk duct ive noticed my son roots constantly and is going less then an hour between feeds. when he's not feeding he's quite often crying and rooting to the point where he becomes quite frantic until he's offered my breast again. on the night he is offered a formula top up and often has near on 4oz after his breast feed. he's been putting on weight nicely and whilst at first it seemed his rooting was just a comfort thing now im worried he's genuinely hungry? should i offer a formula top up more regularly whilst im treating the blocked milk duct? advice much appreciated!
