Ella is really hungry today, she's fed loads, drunk me dry and still isn't asleep for tonight. Really really don't want to have to give her formula tonight as I've managed for over a week without having to top her up, but I don't understand how I can have enough milk for her one day and not enough the next. I really need more milk, at the moment I can't get the chance to express anything to put back without having to use it within a few hours. How am I ever going to be able to leave her for a couple of hours if I can't even get a feed together for her? (Not that I want to at the moment!).
