Me too - I know I can't count on my first-time's-the-charm fertility to stick around forever. But on the other hand, no way was I ready for a baby in my mid-twenties - you just can't win!
I have to share this link with you guys:

H. has been unbearably grumpy the past week or two. And sleeping poorly. And requiring constantly entertainment, but then the entertainment provided will be deemed insufficient and rejected with loud whining.
And my favorite mama-advice blogger has addressed this topic! It seems that it's super common for babies in the 4-6 month range to be outrageous cranks, because they suddenly realize that they could be mobile and desperately want to be, but their bodies just aren't quite there yet.
So I really hope this will calm down. I wear him as much as I can (and I need to get a woven wrap, I think: I suspect we're reaching the end of the weight range for wearing him in our beloved stretchy wrap.) and that still makes him happy as a clam, but still.
Also - is anyone's baby whining and complaining and fighting the boob? H. has started doing this thing where I'll offer the breast and he'll arch away like I'm trying to poison him, and make eye contact and complain... but then if I just look away and don't respond, he'll latch on and nurse happily. Ahhhh - the 5-month phase is like living with a teenager.
