Due to the fact that I seem to persistently think that anyone with younger kids than me has got it easy and they ought to wait til they're the same age as mine and then they'll know what difficult is, I am beginning to wonder how long this will last. Obviously we can only judge what we have so far experienced but what stage do people think is the most challenging? (and anyone who says just you wait til they're teenagers think carefully - you may be responsible for making dds homeless)
