Before you read my response I would like you to go back and re-read your original post but instead of reading it like it was your own post read it as if it was written by someone else. Use me if you want. Then come back and read the rest of this post. Don't ignore the lessons you learned from childhood. Trust yourself and let your children be loved the way you know you want them to be loved. Your mother has clearly stated what she believes. Fortunately for you and your family your beliefs oppose hers. Do what is best for you and your children. If it is a matter of childcare...there are better choices available. Your husband is supportive of your beliefs though you might have to sacrifice a little. But by the sounds of it I think you can handle it.
Thoughtfully yours,
