rofl re 14 yr old and squeaky toy. You mean ds1 won't always want more train track for Xmas as well?
In answer to the original post, I'm afraid I have found 3 much worse than 2 with both ds1 and dd, but then they were "easy" babies and I probably had it coming! I know people who has v sensitive babies, lots of crying etc and were dreading the twos and threes but then the babies suddenly calmed down and were delightful. I think it's just random really - the only certainty is that they WILL go through something horrendous at some point, you just don't know when. Gosh, isn't parenting exciting!
