My dd will be 5 months next week and she never laughs/giggles? She smiles all the time and is a happy content baby but I can never get a giggle out of her no matter how hard I try! She's done it once or twice quite unexpectedly so I know she can do it
other babies I've seen around this age seem to be laughing loads by now but my little lady just doesn't seem to want to its like getting blood out of a stone! This is normal right? Anyone had this experience and did they just start laughing more later on?
