Check out the free Parenting Ages and Stages App for Smart Phones. It is by the folks at Parenting magazine and it is very cool. You can download your child’s age and receive messages that are customized to your child’s age and stage of development. It has great topics like how to tell if your kid is gifted and how to tell if your baby is left or right handed before they are born! Topics cover issues from pre-natal to the school years. I particularly liked the “5 Big-Kid Discipline Dilemmas –Solved”.
