I have been pumping for a week now and have been getting 1/2 oz per session. I started to bf on Monday with a shield (advised from LC). Last night she woke up every 4 hours to feed when it was 2 hours prior to pumping/BF. I am wondering if she is eating too much which makes her sleep more. I have been giving her 3 oz formula plus bf. Should I reduce the amount of formula to 2 1/2 oz since now I am bf as well? I am wanting to wean her off the formula but thought maybe she would let me know when she was full but she just keeps eating.
