A.G.
I hope this isn't a repeat but this worked with my son. I had his dad take him places or do things with him that were special father-son time so that he could start to establish a stronger bond with daddy and now he prefers daddy to put him to bed or other little things about as often as he prefers me. Some things that they have done are: going to the movies or out for ice cream or to the park, playing trains, army, sword fighting (with the foam swords or swimming noodles cut in half), going to a tumble class together, and playing with playdough. I hope this helps, every child can greatly benefit from one-on-one time with each parent.
