Thanks Bex, that really helps. I normally DF 3 hours after her last feed - so usually that's 10.30pm. I know full when if she wakes before midnight, she's just unsettled, even at 2am last night she wasn't hungry. I'll pay close attention to this week's NFs and decide upon a realistic time.
Should she wake hungry, I'll feed and then shh/pat back to sleep rather than allow her to suck. I only mention PU/PD as I know she can really cry when she doesn't get what she wants (boob) so I'm preparing for the worst, hoping for the best.
