Probably, one of the surprises that you have received from your parenthood is that your face can do weird things.
And another surprise is that you like it because when you smile, stick out your tongue, make funny sounds or any other thing to attract her attention.
you will see how your baby looks at you, giving you all her attention. Perhaps, in a few weeks, she will imitate your silly faces, and even, try that you do something doing it first for you imitate her.
Enjoy those moments and your ability to do silly faces!
