I totally agree with the other girls, and wanted to add one thing that I read wrt expressing, when looking into it for my sister who was expressing for her premie baby, that some people are not able to express if the are setting an alarm to wake up to express, and it is better to wake naturally, and express then, than try to force it. Sounds like you are doing great.

Another thought is that if it hurts, it may be more to do with the size of the funnel thing thing. You can usually get different size ones for the pumps...
