Teaching Aidan to sign

My mother talked Golf and I into teaching Aidan how to sign. It didn't take much persuading, because after reading about it a little bit and asking for other internet parents for their input, we discovered how beneficial this form of communication is. Mom bought us the Baby Signs book and here are the benefits in brief, as written on page 18:

Our research studies, founded by the National Institues of Health, have revealed numerous benefits for families and for babies. Using Baby Signs:

* Reduces tears, tantrums and frustration
* Allows your baby to express needs and share his or her world with you
* Enriches interactions with your baby and strengthens the parent-child bond
* Reveals how to smart your baby truly is and gives you a window into your baby's mind
* Helps your baby develop language skills and speak sooner
* Builds a positive foundation for your baby's future emotional development by helping her express her feelings in a constructive way
* Jump-starts your baby's intellectual development, resulting in a higher IQ in elementary school
* Boosts your baby's self-esteem and self-confidence

We will likely start Aidan in a few months, when he's closer to nine months old, but it all depends on what the books recommends too. I've only read the first 20 pages or so, so I don't really know much as of yet. I'm very excited about starting Aidan on this learning endeavor!
