And if so, at what age did you start noticing that? My five-month-old's EI therapist asked me today whether she kicked her feet and smiled when she saw me at daycare. The answer is no. She looks at me, but doesn't smile at me or kick her feet. Sometimes she smiles and laughs at her teachers when we get there, but there's not a real reaction to me at pickup. Now I'm scared that's a sign of another problem. Any insight?
