Hi,

It sounds like you are really doing well to stick in with breastfeeding -I am sure you have experienced significant weight gains. Good on you for breastfeeding before/after the bottle feeds.
The nurses advice was basically advice that would result in you prematurely weaning your baby. The quantities she suggested would mean that a baby would get all her requirements from the bottle and would be too full to breastfeed.
I wonder how many feeds she is having now in 24hours? Usually babies this age would have more than 8. You might consider cutting out formula altogether at the daytime feeds, and being prepared to feed her more often. Many mothers like to keep a "before bed" bottle - they like the feeling of being certain their baby has had a certain amount of formula and is full and will hopefully sleep a bit more.
Keep doing the great job you are doing - have you been in contact with ABA in your local area? They are a great support.
