Granted, it will probably come. But I wonder if it will really make me angry. I fully expect that at some point my child will try to test my limits - it's basically his job. But knowing it is what he has to do, maybe it won't really make me angry. We'll see.
On the other hand, I wonder if the time aspect won't become better over time. Right now we have to watch the baby all the time to make sure he doesn't hurt himself. But there will be the time when he can play by himself of with friends. Of course by then there are also a lot more things we could do with him, which might induce us to spend more time with him in turn.
I am a VERY laid-back person. I don't believe that kids exist purely to manipulate us, and I do believe that a lot of what some people think is "misbehaving" is just a kid's learning journey (exploring emotions, boundaries etc) but even so... wow. I've found patience I never knew I had.
