My two smaller children go to Mount Primary and it is indeed a good school, with a number of excellent staff. I think that your daughter would enjoy the ethos of Mount, and the school is always striving to improve parent-school relationships and I think any school that can say they can improve on something is a good honest school.
My eldest son goes to St.Mary's which I cannot reccomend enough, the school really outshines any other in Wallasey in my opinion.
As Arwen says, St Andrews has all sorts of activities going on and my daughter goes to rainbows there. There is also emmanuel church further up the road that does brownies, rainbows etc! There are masses of football clubs, tennis clubs and really any other intrests your children may have. My dughter attends an amazing dance school, which is very low pressure and fun. If you want any more info just PM me and i'll do what I can to help.
