D.S.
If you're a new mom and you have a baby, life gets easier as the child gets older. I remember life being really hectic when my son was a baby but now that he's three things don't seem so bad. That may be because he's more independent, that I've gotten used to it, or that we've made adjustments along the way to reduce the stress, or a combination of all three.
In terms of adjustments, I have just made the conscious decision to focus more on my family than my career/job, and that has had a big impact on our homelife and my personal stress level. I have always really defined myself by my job, and pre-child worked extremely hard to be at the top of my game. I still want to work full-time and have that aspect of my identity, but right now I am not going above and beyond. It may mean that I sometimes disappoint people at work, but I'd rather disappoint them than my son any day.
