If I could walk/rock my babe to sleep, that would totally be my first choice. He doesn't like being in the sling for bedtime now. It used to be the one sure way of getting him to sleep. If I put him in the sling he will try every trick in the book. "Down!" "Drink" "Potty" "Bjambjam" (peanutbutter and jam). Anything but putting his head down and sleeping

It's a funny thing with the signing... we signed and signed and he would watch my hand sometimes... and nothing. Then around 10 months, he literally EXPLODED signs everywhere for everything. The first signs he did, he was signing to himself, and wouldn't show me. It was almost like he wanted to make sure he had it right before he showed us?? He started by signing the most important ones, like "milk" (boobas) "water" and "potty." Then we started signing A LOT with him, and he only had to be shown a sign once. His signing vocab was around 20 signs at that point. We included bath, bed, blanket, cat, farm animals (we live on a farm, so it really sunk in signing the animal while saying the noise it made). Then, we were on a trip and he was miserable in the truck. We broke down and bought a dvd player for the truck, and a signing dvd. WOW. He was signing to himself the whole way, and used these signs from that point on. Since then we have bought more signing dvd's for the truck, and we actually have to go back and watch them because we need to learn the signs he signing to us so we can sign them back properly. Obviously, at a year old, he doesn't sign them perfectly, but beause he talks while signing, you can usually tell the difference between say, "dirty" and "apple."
I would say it's an awesome idea to teach signs to any age of children. There are so many benefits to having another language, especially one that isn't spoken. I can sign "no touch" from across the room, or "sit down" and he will (usually) do it. Which means no yelling across a room! Also, at our parent group, there is a 5 year old special needs child whom others tend to ignore because of the communication barrier. When she met Skyy, she was signing to him and signing excitedly to her mom. Skyy had never met another child that signs, so he was happy too

Then we had a similar experience on the ferry with a deaf child. I was watching him play in the child area, and he was signing to himself about something. Because he is so young, his signs are not too clear, and I saw this little girl staring at him so intently with a strange look on her face... Then she figured out what he was signing to himself and signed something to her mom and pointed at Skyy. Her mom came over and asked if he was deaf too. I said he wasn't, and she asked why do we sign with him. I explained about bridging the gap between when he WANTED to express himself, and when he could actually verbally do it. She thought it was a great idea and said it would be nice if we could take him to a deaf preschool so other moms could meet him. She said it would be great if more people would do that

Here's some signing resources:
http://www.babysigns.ca/ This was the program I bought at Chapters when he was born. It includes 4 board books, dvd's and a quick reference flip chart for the fridge. It's awesome. A good place to start!
I can't believe I bought these because in principle I'm against Baby Einstein, but I did buy two signing dvd's they had because they were signing. Skyy really loved them. The animation is slow, which is perfect when they are first learning. Now that Skyy knows the signs, he doesn't like these ones anymore, and will actually sign "more signing," which means he wants a different signing dvd on.
When you're child is ready for something more advanced, there is a whole tv series called "Signing Time." It's pretty advanced, and it's not just showing one sign at a time. They string signs together, and sign songs too. Skyy loves this one because there are LOTS of signs. I HATE IT!!!! The woman on there drives me nuts because she talks like the children are dumb. You know, in that weird singsongy voice that so many adults talk to kids in?? I don't talk like that with my son. But, this series is the one he has picked up the most words with. There's two seasons I think in total 14 or so discs. I got mine on ebay.
