Not Done Yet

At this point, Nicholas is 9 1/2 months old. And I have been able to feed him with no problems until now. Since we started making him sleep through the night, I'm missing 2 feedings that he used to take. And my milk supply has tanked. :( My goal was to feed Nicholas at least as long as I fed Ryan (10 1/2 months). But, with a month to go, I'm not sure if we are going to make it.
Really, it would be very convenient in a lot of ways to be done. I could go out without worrying about when or where to feed Nicholas. I could leave for more than a few hours; I could drink coffee again.... So, what is my problem?
I think it is the fact that there is no choice here. With Ryan, I had been supplementing for awhile and he decided one day that he was done and quit cold turkey. His choice--and you can't force a baby to eat. I've tried.
This time? Not my choice. Not Nicholas' choice. I'm frustrated.
But, it isn't over until it's over. I'm not down for the count yet.
