I don''t know what an individual judge would do. Courts aren''t that interested in parents finding fault with each other, they just want to find solutions. Many parents simply don''t understand what is reasonable to decide themselves and when they need to inform and consult the other parent.
Initially courts tend to try reason and persuasion, then move onto more stern talking and threats when orders aren''t complied with. I do think that changing nurseries without consultation might persuade a judge to attach a condition about informing and consulting in relation to choices of education in the future.
