Hello ramo80, thanks for your question.
Yours is certainly not a textbook case, and I’m afraid I don’t know of any conventional wisdom for your particular background.
My advice is to make sure your GPA and GMAT score are in line with the programs you apply to (you would like to be around the mean or at least within the middle 80%).
Otherwise, where did you work before having your baby? I think you would want to demonstrate to the admissions committees that you have the support to handle the rigorous workload while balancing family responsibilities and that your skills and knowledge are fresh enough after a 3 year break to contribute in the classroom and your study groups.
I am happy to comment further with additional information.
Best of luck,
