Winter - DD1 was EXACTLY like that - every single thing was a battle. Believe me, they do change. I almost fall off my seat some days when I now ask her to do things and hear "OK mummy" and "you're welcome mummy". She is really turning into excellent company and is a joy to be around a lot of the time. Between 2 and 3.5, it was a really, really hard slog and mothering felt like a chore rather than the pleasure it is now.
