I use music with Jesse during the day.. we have one of those fisher price aquarium thingys and the music from that seems to relax him.
But dont be too upset with yourself about not being able to settle him.. although Jesse is a good sleeper at night, there are evenings that neither myself of DH can settle him.. he just crys and crys no matter what we do.. usually in the end we just have to sit with him and let him cry and he ends up talling asleep. I think they refer to this at the Witching Hour or something. So dont worry, just take a deep breath, as youre not alone
