we lived on the Gruffalo for 6 moths - night after night - even acting it out! then came 'We are going on a Bear Hunt' - that not only took over night times, its one we acted out when out walking. Even today with my girls at 17 and 14, when out walking and we have to cross a style or bridge etc - they sing out - 'we can't get over it, we can't go under it, OH NO MUM! - we will have to go throught it....lol happy memories :)
