Things I'd do again:
not worry about if my house was cluttered, and get right in there and actively play with my children - tv was rare if at all til after age 4 or so, and even now it's a treat
encourage them to use what toys they have creatively, and not to buy every new thing that comes out
help them learn to respect and care for what they do have
help them learn to express themselves through drawing and art - I can't draw well at all, but I joined in with them and I think they realized you don't have to draw perfectly for the end result to warm somone's heart
help them learn that it's ok to have differing opinions as long as you're polite in expressing it
What would I have done differently? I think I was a better parent before I went back to work, but I got divorced and had to support myself and the girls. I still regret having to put the youngest in daycare though.
I think I'm one of the luckiest parents alive, my kids have never thrown a tantrum in public, never shoved beans or similar things up their noses, never cut their own hair, not poked anything in their ears... I don't think this is due to me, I think it's simply their personalities. The thing is, they were so well behaved as small children, that I don't handle it well when they don't listen sometimes - I'm still working on that one now.
I guess my point is, a lot of parenting isn't what one should or shouldn't do, it's about setting your goals in a way that suits your child's personality. What is right to help one child learn to be a good person, may not help your second child - you have to adapt to them somewhat.
