I think it is totally fine to be offering the EBM, especially at this early stage when weight is so so so important. What you said I totally agree with, ideally your LO would be BFing but until you can get that sorted (and the LC will help you with that) then it's a good second option IMO. Your attitude is wonderful, you sound so positive about getting this sorted and I am so impressed.

Congratulations on the birth of your son and enjoy these early days.
