Oh it def depends on the child. My first was pretty textbook really, on the whole pretty well behaved, needed a lot of attention, broke a couple of things, one very minor trip to A&E.
my second has sn, was very withdrawn as a toddler, happy to sit and stare into space and didn't every break things and was generally very easy to look after.
then I had twins. One isn't too bad - the second is a nightmare.
All four of my kids have been brought up pretty much the same. Unfortunately I wasn't really planning nos 3 & 4, so by then I had bought some pretty nice things. Glass furniture, crystal, good quality electronics, - yknow the sort of thing you buy AFTER the kids have grown up.
dt2 has left his mark on everything! In the past week he has broken a denby rice bowl, stuck a dvd in the toaster, and broken the drawer on a £500 stereo. He has dented leather chairs, chipped the glass on the furniture, smashed cystal vase, jumped out the first floor window, taken heart tablets, blown the electrics, broken a wii and a dvd player, the grate on the fireplace, the windows on the playhouse, an electric quad bike, etc etc.
I don't think I'm a bad parent. I get compliments on how well behaved my older two are, and how well mannered they are. Some children jsut are extremely lively, and you have to go with the flow. You can try putting things out of reach, but mine seen it as a challenge! Luckily he is starting to slow down a bit now. Hopefully the house will still be standing at the end of it.
You really don't know what you will get. There will prob be times when you feel like throttling your child! But when it is your child, you find ways to live with it, even if that does mean turning your house into toys r us. For my sanity, I used to put everything away at the end f the day, so at least then I could pretend I was in a nice adult house once they were in bed.
