My son is 7 weeks and 3 days old now and obsessively clingy to me. His daddy works almost all day from 7am to 5pm. He was good about going to daddy or anyone else until recently. His grandparent went on a trip. Now he won't go to anyone. He'll scream and scream until he comes back to me. Is that normal, just a phase? Any suggestions on what we can do so hell at least go back to daddy.
