Just thinking.
My dc are older now and I'm very glad. I've always needed my sleep and thinking back to the newborn stage it was so hard. Wasn't so bad with my first who would feed and then go back to sleep. But with second I was exhausted, baby didn't sleep through properly for years, then still had to be up early with dc1, no chance for me to nap during day.
Thinking back to those days, I felt very alone in the exhaustion and sleep deprivation, it didn't seem to bother some people so much.
I can distinctly remember speaking to an older lady one day in the park when dc2 was a few months old. She commented that it's a shame they can't stay babies. I commented back about it would be great if not for the lack of sleep and she looked at me like I had two heads.
Also hear lots of people saying the newborn days are the easiest. Lots of people, my mil for example just seem to go mad over a baby. When I see a baby all I think is that they're gorgeous but I'm glad I don't have one anymore.
