Leos are easy to spoil.  They just expect it in such an unpretentious way that you feel as if it's your duty to provide them with anything they need.  They are generally good natured, but like that cute lion cub, can have quite the tantrum when displeased.  After all, they are a Fire Sign and can display a healthy temper when provoked.  Remember that Leos are ruled by the Sun which is the center of the solar system.  Thus, if they get plenty of attention and believe that they're the center of the universe, chances are things will go well.  However, if they're not your only child or you have other distractions such as a day job meaning they have to compete for attention they can get pretty creative in how they obtain it.  Just remember that a Leo child needs attention and praise every bit as much as s/he needs food, clothing and love.

Since Leos truly believe they are royalty, they tend to have a bit of an entitlement mentality.  Again, they aren't always demanding, though they can be, but they definitely have high expectations.  The older they get, the higher the expectations.  That appetite for attention can also increase with age.  They like to be noticed so don't be surprised if your little (or not so little) Lion dresses quite outlandishly once they reach adolescence.  Now lots of kids will dress in a manner that parents frown upon, sometimes because they can't match their clothes, others because they have a favorite shirt they won't allow to be laundered, or they just have weird taste.  Leos, however, will have generally good taste except they'll want to be stylish.  They also like bright colors.  In fact, it's a good idea to paint their room in nice sun-shiny colors, even something like red or orange that you might not be able to stand yourself.  Even if you have to put on sunglasses to go in there, accommodate them in this way.  They can't stand a dull environment, which they'll find horribly depressing, so it's in your best interest in the long run to indulge them, like it or not.

Leos are natural leaders, which shouldn't be surprising, and as such they tend to be bossy.  Depending on other influences in their Natal Chart, they may accomplish this is a brassy or loud manner but they may also take control in a less assuming way, but they will get their way, whatever it takes.  Since they like to be surrounded by their adoring subjects, they tend to get along reasonably well with other children, especially those who tend to follow rather than lead.  Whatever you do, don't discourage your child from being a leader.  They're going to do so as second nature anyway so accept it and do everything you can to teach him or her the responsibility it entails.  Teach them honesty, kindness, and understanding so they don't lead others astray. 

Don't underestimate how sensitive your little Lion is.  They get their feelings hurt quite easily and can lick their wounds for a long, long time.  They tend to be creative and like to make presents for their loved ones.  Always accept them as if they have given you the Hope Diamond.  Foster their creativity however you can.  Whatever they take a liking to, let them pursue it and show off their work.  Even if they're only a toddler, it will mean a lot to them to have their work of art displayed proudly on the refrigerator.  Brag about them in front of others and watch them shine.
