Hilarious! Turn to a tractor website to ask about kids!!!

Well, I have a 3 yr old girl and a 7 month old boy, so I know a far bit more about kids than tractors. I strongly agree with RobJ and KubotaSteve on their posts. Here's my list based on my experience, not in any particular order:
1.) Don't compare what your kid is doing to every other kid close to their age. They are all different. Your cousin's kid may be walking at 7 months (mine's was) but may not be talking good at 3 years old. My little girl never crawled until the week of her 1st birthday. She'd just sit there content to play with her toes, but she can carry on a conversation with you like she's 10 years old. They all develop at different rates, just enjoy her.
2.) Get a digital camera if you don't have one, and a digital video camera if you can afford one. She will grow up so fast your head will be spinning, so take lots of pics, digital is cheaper in the long run. You will never look back and wish you had fewer pictures of her.
3.) Sign language.... some may disagree, but we taught our girl to sign. You'd be amazed what they can learn WAY before they can talk and ours was an early talker. She could tell us she needed her diaper changed before she was 8 months old. Instead of crying, she'd just sign, and we'd change her. When she wanted more food, she'd sign "more" and then point to what she wanted, no screams or grunts, and she learned to say please before she got what she wanted. I'm telling you, it was awesome to communicate with her that early. I think it helped her verbal skills and reasoning skills as well, because she was learning and interacting, not just crying for what she wanted.
4.) Let her
learn to fall to sleep. This is kind of on the "let her cry" theme. If you put her down for bed while awake and let her learn to fall asleep on her own it will help down the road. Rocking to sleep is sweet and fine every now and then, but I have cousins who still have to rock their 3 year olds to sleep EVERY night. That is insane. Ours are trained, when put in bed, to go to sleep. That is different from just letting her cry all the time. When she needs something, tend to it, hold her a bunch, but when its time to sleep, let her cry now, it'll save LOTS of crying later.
5.) I'm neutral on the passy thing. We didn't let either of our kids have passy because I hate them. However both suck their fingers now. The beauty of the passy is you decide when to take it away. We've tried everything to keep my daughter's fingers out of her mouth - that nasty tasting fingernail polish, sewing socks into her PJ top - nothing has worked.
6.) Breast feed/bottle feed, there are pros and cons. My wife wants to be super mom (and is pretty close) so she did/does the breast feeding rout. Cheaper for sure, but you can't always just take off and do stuff. She's modest so she doesn't do that in public. And pumping for a bottle is a pain in the rear. If you can deal with the inconvenience for 6 - 12 months, it's the way to go, but if not the kid will survive on formula. I came home from the hospital on 2% cows milk because I was allergic to the formula back then. I survived, and other than not being able to weld, I'm doing pretty good. That thing about there being lots of people on this planet AND lots of morons - kids are pretty resilient.
7.) There are a million kid-gadgets out there. My philosophy, if they didn't need it on "Little House on the Prairie" they don't need it now. (I use that because it's my wife's favorite show.) We don't use child locks on the doors, toilet seat etc. We simply teach our kids what not to do and they obey. If it's life and death, sure make it safe, but for general stuff kids need boundaries. Don't be afraid to tell them no. They need to learn that word. It won't kill them.
I could write book, but better wrap it up. Love your kid, spend as much time as you can, but be a parent not a buddy. She'll have lots of buddies, but only one dad. Sometimes it stinks to have to be a dad and say no to things, but it's the right thing to do.
Congrats man. I hope you get as much enjoyment from her as I have from mine.
