Well, I'm taking the plunge and going to choir practice tomorrow night and leaving DS in with his daddy. I asked the HV ans she said it would be fine to go out as we've established feeding nicely, and we already know the boy is fine with a bottle since we had early BF issues before getting a tongue tie sorted. I've been expressing and putting a stock of EBM in the freezer. The question is, how much EBM should we give him for an average feed? I do wish breasts had some sort of guage on them to tell you how much the baby has had!
