My daughter is more like your son. But I really wasn’t bragging about it. I’m great at slacking (look, another post!) so I worry that he doesn’t know when it’s okay to let a little bit go. Gotta have some balance in life.
If your son is getting good grades then maybe he’s not so far off of the mark. Obviously not a good habit to put everything until the last minute, but maybe he’s smart enough that the coursework isn’t challenging him.
Our almost-four-year old: Stop eating your boogers (we’re serious when we say it’s disgusting, and no, I don’t want one). And, for God’s sake, when you’ve decided what you want, don’t change your mind and throw a fit because now that we’ve agreed to what you want, you don’t want it anymore. We haven’t let it fly in the past, and nothing has changed to make us let it fly now. And bedtime. Ah, bedtime. You should be asleep two hours after we’ve left the room, not in there yakking at your stuffed animals. And I know you’re tired - don’t think I didn’t see that yawn or you rubbing your eyes.
Our five-month old: Rolling over from back to front and remembering to unclamp your gums and open your mouth before turning your head away from the breast while feeding.
Our six-year-old: Whining and dawdling. And shrieking at your mother when she stops trying to help you with something because of either of the above.
Our almost-two-year-old: Not too much, really. Reprimanding hitting when it happens, but it’s not terribly frequent.
Maybe there will be smooth sailing after they both grow up and move out of the house - but I wouldn’t count on it.
Almost four year old: the k sound, r sound, and g sound. After a month or so of speech therapy she is doing awesome and starting to correct herself on her own.
35 year old parents: realizing that although she can do many big girl things now like using the bathroom, dressing herself, bathing herself (supervised), etc, she is still just a preschooler and will act that way at times. Sometimes I think we should have videotaped some of her more awe inspiring terrible two (ok, 12 month to 3 years) tantrums so we could be reminded of just what a terror she was at times.
Yup. I am (still) working on accepting the fact that there will always be something that needs, well, working on…
My kids are 20, 18 and 12.
20 year old Daughter: keep up the grades, learn to RELAX a bit about grades and enjoy some of college. Find a boyfriend (because she wants one). Um, I’m not finding the BF for her, just to be clear…
18 y/o Son (#1 son): Figure out which college (has to choose–he’s been accepted to both). Keep grades up. Keep job. Keep GF, best thing that ever happened to him. Don’t drink and drive. Please use condoms. Talk to us.
12 y/o son (#2 son): Keep up grades. Stay connected to friends. Don’t live in the basement on the computer (I still control this, I know). Engage in social activities. Keep talking to us. Wash your hair. Use deodorant. More of it.
But seriously, I hope all my kids find happiness in their lot in life. What else is there at the end of the day?
I’m still trying to get mine to stop stepping on cracks- they know I already have back problems! 
13 year old: getting him to do his writing, and bathe himself, period. He likes to wear the same clothes over and over and over. Stop being an interrupting cow.
15 year old: better at hygiene, but she needs to shower more often. Her hair is just greasy all the time. Figure out if she’s actually one of the lizard people because she’s the complete opposite of her brother in every way.
12 yr old: do your homework; there is a life away from the computer
9 yr old: remember to engage your brain before acting; the real world is this way
My twenty year old: Trying to get her to be more independent and assertive.
My five year old: Trying to keep her from saying “titties” dozens of times a day. Trying to keep her from grabbing mine and other people’s breasts, and trying my best to keep her from assaulting her teachers. She’s a little firecracker.
2 yr old: listening and obeying simple requests. He understands perfectly well, he’s just terrible at paying attention and being anything like obedient. Also food wars plus diabetes and trying to keep his blood sugar stable are a little wearing. We’re working on him telling us how he feels, so he learns to pay attention to his body signals. It’ll help avoid blood sugars highs and lows eventually.
2 week old: three hours of sleep in a row would be nice. Actually, he’s a pretty good baby thus far.
8 year old: Keep temper under control. Talk about what’s bothering her without a screaming fit.
2 year old: Potty training. Follow directions without saying “I don’t want to!”
5 week old: Sleep through the night. 
4 year old: paying attention when people are talking to him, rather than gazing off into some more interesting alternate world where pirates riding dragons are fighting knights (as opposed to daddy saying ‘please get out of the car now’).
20-month old:
Using utensils. Getting much better at it lately, at least until she’s full and then switches into “food flinging” mode.
Basic coloring. I don’t know why, but she’s not a coloring fan.
Saying her own name. When do children normally do this? She knows it’s her in the mirror, but any pictures of her are all referred to as “baby”.
Potty training. She’s just about got the idea of what it’s for. Next is to get her to do something about it.
Reading. She recognizes all the letters of the alphabet so occasionally we try to see if she can identify small words. This is not something we’re pushing on, though; there’s plenty of time yet.
Not destroying the house. Yeah, I know - good luck with that.
Just this morning she offered us a whole new set of things to worry about, including crying at the sight of “mild peril” on television (a talking train had to brake suddenly to avoid some squirrels (who were fine) and spilled some logs from a flatcar; this was enough to start her off) and a fear of changing tables (making me wonder if something happened at nursery yesterday they didn’t tell me about). It’s always something…
