DD is nearly 5 months old and exclusively breastfed. I used to give her ebm top ups, but she has not had a bottle now for over 3 months.
I have to go out one evening next week, and leave her with DH - I'll be gone probably 2-3 hours at around the time she has her last feed and goes to bed.
I've never left her before for more than an hour, or at such an inconvenient time.
Some questions: I'll have to express milk for her last feed - how much milk should I be aiming for 
I haven't tried expressing for the past few months either - should I practice that beforehand? I am a bit wary of overstimulating my supply or something, but I don't want to find I can't get any out at the crucial moment.
I'm worried she won't take a bottle, although she took one happily enough when she was younger. Ought we to practice that too, or just assume if she is hungry enough she will drink it?
