I like it, it's very fresh and pretty without being too frilly. I know one who's 4.
People always comment on threads about this name that Aprils must be born in April, but that's rubbish IMO. You get Mays and Junes born in the winter, and Hollys and Ivys born in summer; April is no different to me. I actually think it's better if she's not born then - bit twee if so.
