What period has been more difficult?

Curious to see what people deem as more challenging.

I’ve had sooo many other moms warn of like “oh just wait til they’re crawing/walking—that’s when it really gets hard”

I don’t see it that way at all. He is SO much fun and even though I have to watch him for safety at all times, this is easy peasy compared to spending all my waking hours calming down a fussy baby and being up all night!
