With Charlie, the infant stage was harder just because I was figuring out how to do this whole parenting thing. Also he was pretty easy through his 2's. It actually got a lot harder in his 3's, but in a different way than the infant stage. It was like the hardest moments were way pull your hair out harder, but there were also a lot of easier moments because he was more independent.

With Olive, the toddler stage was harder. She was a mellow baby and very late in hitting physical milestones, so she was pretty easy. Once she became a toddler, tantrum central!

I'm sure it partly depends on the temperament of your child, but which was harder for you?
