I def believe in this kind of thing and i think they were popping by to say they enjoyed the party and they are always there.

My DD's middle name is after my great grandmother and i often hear DD awake talking at night after i have dreamed GG has been watching over her.
DD is only 10mths old so it's cute garble rather than talk... hehe

I hope you get to smell the smell and enjoy the watch many more times to come.
