My daughter is 4 weeks old- I initially started breastfeeding exclusively but was recovering from an iron deficiency and was just not producing enough milk. On the advice of several people including the midwife I started to top up her feeds with formula so offering her 1-2 oz after each breast feed. So far this seems to be working really well- I am now steadily increasing the formula to 3 0z but still starting with a breast feed on each session. But i feel really guilty! And unsure about how to progress. Do I just keep on increasing formula? My boobs are still producing milk but i'm aware that the supply will be less as I've been combining. Anyone else done a bit of both?
