Hi A.. Because you tickled him? Man, that is an old wive's tale if I have ever heard one. Your son is fine. My son is going to be 2 in September and he barley spurts out anything. All the mothers on here told me not to worry. Some babies talk faster than others. He babbles like a brook too, but when it comes to getting the words out of him....well, it hasn't been too good. I started saying things funny...like I'd say, "Jake, you want a bath? (on the word bath I'd make funny faces and kind of high pitch scream it). Now, he'll tell me BA-BA!! and point to the bathroom. Just give your son time and patience...and forget about that tickling thing. Even a doctor would tell you that is nonsense. Good luck and Best Wishes, T.
You know, before I sent this I happened to read through it again. If your baby is only 5 months old, you surely don't have ANYTHING to worry about. Most babies I know don't start talkign until at least 1 1/2 years old. Bye bye.
