My baby is 6 weeks old. For the last 3 weeks I've been having problems with blocked milk ducts in one breast. Everyone I asked for advice said I should feed as much as possible from the blocked side and consequently I think that my supply has reduced in the other breast. Yesterday I was diagnosed with a breast abscess in the blocked breast and advised to stop feeding from that side until it is treated. My baby seems very hungry and unsatisfied now that I'm down to one breast. We topped up with formula last night (Cow and Gate ready mixed formula) but it seemed to give her a tummy ache, as it did the one other time we gave her formula. Does anyone have any tips for increasing supply quickly or for brands of formula that are less likely to disagree with her? Thank you.
