Indeed one is the most important act of worship is upbringing of our children. Children are trusts from Allah and parents will be questioned on how they raised their children.
Both father and mother are equally responsible.
Consider the following points:
1. Let your children see in you what you want to see in them
2. Show priority to their madrassah studies
3. You and your husband should invest your time in teaching them Islamic values at home.
4. Always take them to Islamic programs
5. If you feel the environment is harmful, there is no harm in moving to more suitable and convenient environment for their upbringing
