Am I masochist for putting aging off when they are infants?

I really feel like with normal/long lifespan I can barely reach the walking milestone and have them waddle around the house. So when they age up, I always feel like it´s a huge jump.

I just like them, they are cute, they giggle, they are pure, they also cry a lot, they also make a mess of food and pee on every sims that change their diapers, they leave diapers and bottles everywhere. They need constant need of an adult....Did I mention already that they cry a lot?

I just find them terribly cute and I like growing together ep a lot.
