In the evening, the room became just a little quiet.
When I turned around, thinking, “Huh, what are they doing?” my 2-year-old was gripping a plastic bottle tightly with both hands.
It was the cap they could never open before, the one they would quickly hand to me and say, “Do it.”
But that day, for some reason, they were silently and intently twisting it all by themselves.

💬 Just When I Thought It Had Gotten Quiet

In the evening, the room became just a little quiet. When I turned around, thinking, “Huh, what are they doing?” my 2-year-old was gripping a plastic bottle tightly with both hands. It was the cap they could never open before, the one they would quickly hand to me and say, “Do it.” But that day, for some reason, they were silently and intently twisting it all by themselves.

🤔 Have you ever found that when your child is quiet, they’re trying something new?

Then there was a tiny squeak, squeak sound...
And pop—the cap came off.
With a huge smile, my child showed me and said, “It opened!”
Before I knew it, I said, “What, you opened it?” and I felt both happy and surprised at the same time.

💬 The Unexpected “It Opened!”

🤔 Have you ever been surprised with “Wait, already?” before you even had time to feel happy about a new milestone?

Once they could do it, things moved quickly from there.
The water they had just been drinking, the empty plastic bottle on the table, the spare drink I had kept in my bag.
Every time they found one, their little hands reached for the cap.
Growth is wonderful. But as I wiped up the spilled water, I realized, “This is something I really can’t take my eyes off.”

💬 Growth Quickly Becomes Part of Everyday Life

Once they could do it, things moved quickly from there. The water they had just been drinking, the empty plastic bottle on the table, the spare drink I had kept in my bag. Every time they found one, their little hands reached for the cap. Growth is wonderful. But as I wiped up the spilled water, I realized, “This is something I really can’t take my eyes off.”

That night, I changed where we kept the plastic bottles.
Because the caps are small, I decided to put them away right after opening them.
But even as I tidied up, I kept thinking the same thing in my heart.
Something they couldn’t do yesterday, they can do today. It makes me happy, and it’s a little more work—and I thought, this is what being 2 years old is like.
