Hi E.,
Looks like you already got a lot of good advice. I'm a mom of 6, soon to be 7, kids, so we've dealt with lots of tantrums. I definitely agree with the strategy of not giving the attention to the tantrum. At this age, they don't understand time-out, and you really can't reason with them. Plus, you don't want them to associate the crib with negative emotions, because then you'll end up with sleep issues. As long as your child is safe, just let him have the tantrum. You can stay nearby, but don't let him know you are paying any attention. They de-escalate faster this way. However, I also have heard wonders about teaching them some simple signs at this age, because the tantrums are usually just a frustration at not being able to communicate. If you are afraid he will hurt himself, you can hold him on your lap, not facing you, and if necessary hold his arms down firmly but gently, telling him that you are going to hold him until he stops. I've had to do this a couple of times, and it seems to help, especially if it's already escalated out of control. Isn't motherhood a grand adventure?! Good luck to you, and remember, this too shall pass.
