That's me, knocking at the door

I peeked in her thoughts
Where my room was taking shape.
Prams and cots and disney wallpapers.
Sometimes she planned it blue,
Sometimes a lovely shade of pink.
Occasionally I would hear her sing lullabies,
Rehearsing for impending sleepless nights.
Hear them both find  me a name,
I really loved some, but there's no way I can tell.
They build me a home in their hearts
And I bask in the glory of their love.
The riotous joy that I am,
I laugh at their planning things post my arrival,
Little do they know, I will mess it all.
And on weekends, I find them shopping
Feeders, diapers and clothes,
Their faces aglow with sheer happiness.
A little bundle draped in a pink sheet,
I enter their lives,
Expanding their horizon manifolds.
My mother crying in pain and then in pleasure.
My father looking at me with sheer joy.
Seamlessly, we blend in one embrace,
A happy little family.
