Girls, what age did your kids start calling you directly "Mom, Dad"? Mine if something wants comes and grabs her hand shows if something is needed but still no such "Mom" ? What she wants and needs she just shows or on her own. Do I need to be alarmed? Although I always ask specifically like What do you need? What do you want? I say tell me "Give Mom" etc. How it's that she stopped saying "Dad" and "Mom". Recently again went. But only Dad ? Mom extremely rarely. ????? what to do? I spend every day with her: Show pictures and pronounce animal names, she has no interest. If
