I know how you feel, it's a tough job to tackle when they are infants, but I promise you that it goes by quickly. And, you will miss the infancy stage. I never thought I'd wish for my son (who is now 7 years) to be an infant again, especially being that he was very colicky, but I do miss those cuddle times. Now he's "too big" to sit in mommy's lap and cuddle. :( Hang in there, it will get easier and you will make it through it.
