How can I get to know my baby at twelve to fifteen months?

Play. Playing with your child, spending time, talking to them and having fun is the way to go in getting to 'know" your child.
Typical behaviors. The twelve to fifteen month old will pull to stand and cruise along furniture and take some steps. Small objects are picked up with a neat pincer grasp as hand control improves. Vowel sounds like dada/mama come easier now. Fear of strangers is more common now and will persist for at least a year. This is normal and healthy response.
