Raising children requires not only cuddly love, but a little tough love from time to time as well. If you never say "no" to your kids, they'll end up ill-suited to dealing with the real world as adults, so setting limits is vital, if difficult at times. And because all Sun signs respond differently to "no," you must find a way around their unique temperamental quirks!
Aries will argue noisily when told that their adventurous whim has taken things a step too far, and they'll see "no" as a challenge to be pushed aside. Try to turn it into a game rather than forcing your authority upon them.
Taurus is the master of passive resistance -- they may not argue, but they certainly won't budge, either. You'll probably need to bribe them, since indulgences are their weak spot.
Gemini will argue the merits of your case every which way, leaving you confused while they continue with what they shouldn't have been doing in the first place. But they do understand a brick wall when they meet it, so be persistently firm.
Cancer will flood you with tears and leave you feeling guilty that you've made them unhappy. Don't be manipulated by their emotional games. They may be sensitive, but they're also tricky -- so call their bluff.
Leo will crumble if you criticize or say no, which in turn will make you wilt. Boost their confidence while, at the same time, letting them know where the line of reason is.
Virgo will either act the part of a goody-two-shoes who never needs to be scolded, or turn into an absolute crybaby. Just beware that they're adaptable, so endure their initial sulking -- they'll get the message quickly enough.
Libra will be sweetly reasonable, though they have a steely core and, at times, even a sharp tongue. You'll need to argue the merits of your case, at which point they're bound to give in.
Scorpio may smile blandly, but it's a given that they're going to dig in their heels and protect their back. Expect some difficulty getting your point across to a Scorpion!
Sagittarius will argue, stomp up and down and generally act prickly -- after all, Archers resent limits of any sort. But their aggravation never lasts long, and they'll get in line once they've forgotten what all the fuss was about.
Capricorn understands limits quite well and listens to the voice of authority; at times, you might even wish they were more rebellious. But when they do transgress, they'll listen to reason better and faster than most.
Aquarius is stubborn and independent, so they'll surely defend their corner. However, they tend to respond well to debate and also appreciate jokes, so use your sense of humor with your little water-bearer.
Pisces will not confront you directly, but they can be irksomely evasive when it comes to agreeing to rules. Take the roundabout route rather than putting your foot down -- if you appeal to their kind nature, they'll behave just to please you.
