Do you allow other family members to get in the way when it comes to disciplining your kids?

Hi, I do not allow anyone when I am talking to the baby. I feel when one person is talking to the child on something then no one should budge in between lending advice. And if that family member thinks that I am missing on some major point then he may talk to the child later, but not when I am in conversation with the child. Apart from me, my husband also takes the onus of discipling my kid. And once in a while when she is being very naughty, my in-laws tell her to behave, but not on regular basis. They rather address the problem to me, so it is basically my husband and me who take things forward.
