Ah I see. Those are fun ages. They're little but also learning to be big. And even though you've already had a 3 year old before, I bet it's still a lot of new because it's a totally different 3 year old.
Discussion
Not only different but opposite in character, taste and personality. We as parents are also not the same and at the family level we are completely different (meaning the 3yo was born to a family of 3 already, whilst the 5yo was born as an only child).
It is an adventure for sure.
