My daughter walked at 8 months - the pediatrician was stunned when she walked acoss the room to her. But she didn't speak full sentences until she was nearly 3. My son walked around age 1 - but was talking at a more normal age. My niece didn't even attempt to walk until she was 18 months - but she was talking in full, distinct, completely understandable sentences by then! Each kid is so different. Their little brains focus on differennt things at different times. Some kids have their large motor skills developed early, while some kids are better with their fine motor skills. Some never really develope their fine motor skills all that well (my 11 yr old son's handwriting is abysmal).
My daughter who was walking so early, by the way, does not, in any way excell in sports or physical activities - in fact she's pretty unskilled although she tries. My son needs extra help with his language skills and he's in middle school although he's come a long way and he's a great athlete. So you just never know how it's all going to come out.
My daughter who seemed verbally delayed as a toddler eventually learned, of course, to speak full sentences and her language skills, at age 14, are right in the middle of the range. Her pre-school teacher told me that she was certain that my daughter would arrive at kindergarten with the ability to communicate! ;o)
Unless your pediatrician really sees something that's out of the normal ranges I would not worry about it. You'll get past this mama and chuckle when you remember how it worried you for this brief moment in time!
