Most parents have used the whole spelling out secret words trick with toddlers, but did you know that by the time your little kid turns one, they probably understand about 70 words. Even though they can only make nonsense sounds back, they are listening, so keep up the "baby talk."

The terrible twos filled with arguing, tantrums and defiance. But what makes two so special? Two-year olds have more than 100 trillion synapses, or brain connections, which is the most they will ever have in their lifetime. Instead of fighting with them, use this time to teach them, because they have a lot more going up there than you do. In fact, adults only have half of the neural pathways that a two-year-old has.

Ever heard people say they are throwing an elaborate birthday party for their one-year-old - you know- for the memories? Well as it turns out children’s memories aren't fully operational before the age of three. While stimulating your babies brain is still important for development, they probably aren't going to be re-telling those stories of the time you hauled them around Disneyland at two-years-old.

Peek-a-boo may seem like a silly joke, but for pre-schoolers this magic trick is serious stuff. Their brains have yet to develop logic and perspective, so when they put their hands over their eyes and you disappear, they really think that you can't see them because they can't see you. A much less strenuous game of hide-and-seek don't you think?

As much as you might laugh at what your hilarious kids do, babies and kids take the cake when it comes to getting a kick out of laugh. These prime stand-up comedy audience members can laugh up to 300 times a day. Whereas adults typically laugh at the most, about 20 times a day. So the next time your feeling blue take a tip from babies and look at your feet - apparently they are hilarious.
