These two are already inseparable...it hurts my heart (in a good way) watching them interact.
I think Grace is as concerned as I am regarding Charlotte's refusal of the binky.
Grace just doesn't understand how Charlotte doesn't have one in her mouth every second of the day. So much so that Grace is constantly trying to shove one in Charlotte's mouth. Looks like they both are going to be stubborn and strong willed. Grace won't quit shoving the binky in Charlotte's mouth and Charlotte won't quit spitting it out.
Oh the teenage years are going to be interesting!
