My 4-month old baby shouts too loud now. It sounds funny and entertaining to us. Is she learning to talk now or just need some attention?

Congratulations! Your baby is reaching a new milestone. This is the cutest stage where she is having baby talk. http://www.mayoclinic.org/healthy-lifestyle/infant-and-toddler-health/in-depth/infant-development/art-20048178 Babbling and other new sounds. Babies this age often begin to babble, squeal, gurgle and laugh. Your baby might respond to and imitate your facial expressions and sounds. He or she might babble and then pause, waiting for you to respond. As your baby's memory and attention span increase, he or she will begin to pick out the components of your speech and hear the way words form sentences. Your baby might even recognize his or her name. You might notice changes in inflection or tone as your baby babbles and coos.
