When do babies start talking alot? My daughter is 18 mo and says mama dada and baby, and thats really it. Should I be concerned?

It depends. Not all babies develop at the same pace or reach milestones at the same time. If you ask a group of moms when their children started talking you will get a different answer from each. Some babies take longer to learn how to coordinate their tongue and mouth to form sounds. Try not to worry; your daughter should be talking up a storm soon - and then you'll wish she would shut up!
