DD is 13 weeks old and started daycare this week. I discovered today that they have been successfully putting her down for naps using a pacifier! We did not try a paci until she was four weeks and she just would not take it.
Huge win because while I have been nursing her to sleep, she always wakes up when I lay her down. Had to share my success. If you waited to try a paci after 4 weeks, did it go well?
