My granddaughter is 3 yrs., 9 mos. She is still not potty trained despite consistency in putting her on the potty. She screams and covers her ears when you mention it's time to go on the potty. She also does not seem to know how to interact with other children. She will say hi to them, but if asked a question, doesn't answer or moves to something else. Her speech is fine, she just doesn't use it much If I ask her what she did at the playground, I get no response. If I say "did you play on the swing," she will answer with a "yes" or "no". She can say complete short sentences but simply won't engage in conversation with others. She is an only child and is not in daycare. She is bright, knows all her numbers, letters, does puzzles perfectly after one time with help. But basically I hear her repeating what she hears others say rather than using her own creative speech. I have 7 other grandchildren and am beginning to get concerned about her.
