While I dislike the way society tends to put moms up on a pedestal, I have to say: I kinda get it. Moms are awesome. We're loving. We're capable. We have the magical ability to work within a million different constraints with nothing but our wits and determination and come out with all of our goals met. Being a mom is a never really ending trial by fire, but we see gains year by year. There are, for example, mom skills you'll have before your kid is 2.
Have you ever seen a kung-fu movie where the apprentice has to train under a master in order to learn the ways of martial arts? And they have to go through all these horrible ordeals and at first it's painful and they suck, but by the end of it all they become masters themselves? Being a mom is kind of like that. Also, in this analogy, your baby is a wizened old man with a flowing white beard showing you tough love and, well, that's just entertaining as hell.
None of this is to say you reach your final mom evolution by the time your child is 2. Far from it, actually. My oldest is 5 and I have definitely not seen the top of the mountain yet. However, I can definitely look back at the time between my children's births, and the time they each hit 2, as a period when I was most rapidly developing important skills that would carry through to the rest of my mom career.
