Common Infant Questions Answered
Expert Answers to Common Newborn Questions
How can I tell the difference between a social smile and a reflex smile? About what age am I guaranteed it's a real smile?
"This is a very interesting question and one that is not well studied or documented in medical literature," Dr. Fay says. "There are a few small studies which suggest that reflex smiling is replaced with social smiling at about 1 to 3 months of age. The difference between the two is generally accepted to be eye contact between the infant and the person observing the smile. I'm not sure I can guarantee a 'real smile' at any age, given that studies have shown that humans have the ability to manipulate their lower face for deceptive purposes, and a 'social smile' is one of the best deceivers." When do babies start to see color for the first time?
"Babies see color from the time they are newborns," Dr. Dorsey says. "There have been a lot of studies using color and watching babies' eyes track it, but the bottom line is they see the same world that we do as they enter it." My baby likes to roll on the floor and has rubbed a bald spot on the back of her head. Is this harmful, or should I keep putting her down? Will all her hair grow back?
"This is very common, and happens to any area of the body which is rubbed frequently," Dr. Fay says. "Her hair will grow back, and she will have no long-term problems with her hair because of this."Want to see more?
