Nursing

My baby is 8 days old I'm nursing her and she's doing good and I'm producing really good so far when I pump I get about 3oz every time well my mom is staying with us and she leaving soon and she asked if I would let the baby sleep with her for the night and she bottle feed her with the milk I've pumped so me and my SO can get a good nights sleep before she leaves but I'm scared if I do that it'll hurt me producing milk I'm so scared of that happening can someone tell me if it will or not
