The tongue is the strongest muscle in the body

For the past week Cameron has been obsessed with her tongue. This makes feedings a little more challenging but it is so cute to hold my face up to hers and have her respond to me sticking my tongue out. I can't wait until she starts smiling at me when I smile at her! What are the best "firsts" you've had with your children that you didn't know about? What do I have to look forward to in the next month or two? Or even later?
