My LO is 2 in October and lately he has been laying sideways with his hear on the floor rolling cars in front of him watching them drive by. I googled unfortunately and it said these are "red flags". My LO is a chatterbox, he has perfect eye contact, is extremely social, & communicates with me and my husband fairly well. I don't understand why that would be a red flag. Anyone LO do the same? Sometimes my LO will also "read" a sound board book and repeat the same sounds constantly. Will be bringing up to pediatrician next month. Just wanted opinions. thanks
