It's harder, definitely, but also much better than I expected in some ways.
I didn't expect to feel so much fear and worry. Suddenly the world felt a lot scarier to me and parenthood brought a rather unsettling sense of mortality.
The newborn phase was horrendous for us but improved at around 4mo. I expected to have a content little sleeping baby that didn't use a dummy and breastfed effortlessly. Not so.
I think in all the important ways I am the parent I wanted & expected to be, but the details have been adjusted to suit reality.
DD constantly amazes and challenges me so I am learning as I go!
