With having children there are too many life changing moments of both frustrating challenges and mind bendingly beautiful revelations full of pure love, to list.
As much as you feel you're giving away your freedom, think of it as bringing them along for the ride.

However, do please remember that they don't stay babies and children for long.
They grow up very quickly. It's not tantrums and nappy changing forever :)

You are raising the adult they are going to be, and that's a beautiful journey to be on.
