It sounds as though, from your other question, you may be wondering about toddlers, child development, behaviors, what is acceptable and what is not acceptable, and perhaps how to teach your child.
Discipline is teaching. It is not punishment. Discipline is when we teach them to hold our hands when they beg to walk alongside us in the parking lot. We hold their hands. We tell them that the cars may not be able to see them, and Mommy is here to protect them and make sure that we both get safely into the store. Punishment is when they let go of our hands and try to run free and they lose the privilege of walking like a big girl and they have to now be buckled into the shopping cart. Discipline is when we teach them that we sit politely in McDonald's and we don't throw food. Watch Mommy. Punishment is when they throw their french fries and start screaming and we remove them immediately from McDonald's and they don't get to play in the ball pit or go down the slide. Discipline is teaching, punishment is removal of privileges or dishing out consequences. The discipline must be clear and the punishment must be clear. This applies from the first time they figure out how to throw things and bang their heads until they get their driver's license and cell phones and are allowed to go out with friends.
And what's best for little kids is their parents' time, attention and love. Do you play with your child? Do you get on her eye level and quietly say "we will stop playing this game if you hit Mommy one more time"? And then do you follow through? If you're building with Duplos with her, and she pitches one at your head, do you quietly get up and walk away, and then return when she stops throwing them and resume the play? (This way she learns Mommy and I can play when I don't throw blocks at her head. Mommy doesn't play or talk with me when I throw stuff at her and scream.) Do you interact with her, play with blocks and dolls and cars and trucks and play-doh? Do you let her have a pot and a wooden spoon when you're making dinner, and do you engage her in conversation? When she hits or acts out, do you remove your attention and eye contact from her, and then resume when she takes a breath or stops for a second? Noticed behavior will increase, ignored behavior will decrease.
Do you have consistent rules and consequences, clearly established? Little ones don't understand "behave at the table". They can be taught to understand "don't throw food" or "don't bang your plate on the table". Little ones don't comprehend "get ready to go". They can be taught "go bring your shoes to me. I will help you put them on." One clear direction at a time, not a whole bunch of run-together directions. "Bring me your shoes and then we'll get your coat and do you have your blankie and oh where did I put my keys" will just confuse everybody.
If you're looking for interaction with other moms and kids, take a walk. Go to a park. Go to a library with her. A good day care will insist on some basic behavior standards, and you'll have to implement those same standards at home. So it's best to establish some good behavior patterns now, and then when she's older (3 or so) she can have the privilege of going to a little playgroup or day care and interact with other kids. But first, she needs the security of your clearly established discipline and consequences, delivered in a firm, loving, calm manner. Don't put her in daycare because you can't handle her. Put her in daycare when she's been taught how to behave and she's ready for some new friendships and it's nearly time for her to start pre-school, or because you, out of necessity, need a safe place for her to stay during the day (there are lots of valid reasons for daycare - a sick sibling, a difficult pregnancy, the need to work for income, an established career, work requirements and odd hours, having to care for an elderly or ill family member, no other kids to play with at all due to location, etc., but behavior problems are not a good reason).
