It is right and good for people to have definite opinions about all kinds of things, including the rearing of children, and to freely express themselves, especially with the people they love. It is also right and good for people to respect the rights and boundaries of others, especially others they love.
Approaching the situation with love and respect for all concerned, discuss your worries with your loves. Know what your boundaries are, and express them. Ask for what you need. Give them a chance to love, respect and support you in this area of your lives. You may find they are each glad for the opportunity.
