My first daughter has exceled in a lot of ways (speech, crawling, walking, running, eating, drinking, etc...) and other parents were initially worried about their children in comparison. My daughter has since stopped her accelerated pace and almost all the other kids are either completely caught up with her or almost caught up. So, kids will all catch up in time.
Also, we didn't babytalk our daughter we just spoke sweetly, but we actually talked to her and it seemed to help her develop speech faster.
Plan for about 20 colds and doctor visits in year 1.
It's ok if some days you want to punt your screaming kid down the block. Doesn't make you a bad parent, just don't actually punt them.
If you're tempted to shake your crying baby out of frustration immediately lay the child down in a safe place and walk away and calm down.
A wiper warmer is not necessary (well, in Texas anyways).
Remember that most often Mommy is the lead parent for new baby. If Mommy is breastfeeding you're gonna spend your time as a new Dad doing nonstop up-downs fetching things for Mommy/baby.
If your wife/girlfriend is up feeding the baby in the middle of hte night, get up wiht her while she prepares and go change the baby first and bring her the clean/dry baby.
When you're child is old enough to speak and asks the same questions 2000 times a day keep answering them, keep explaining things and keep being patient....kids develop through repetition.
12-18 months is too young to discipline you chidl - the child won't retain the majority of your scolding so save it for a more months out.
That's all I can think of off the top of my head.
