I have gone back to work full time and my almost 5yo son is not choosing me. He is only choosing dad. Help!

I recently started to work full time since my son was born and he and I are having difficulties transitioning to the new situation. He is almost 5 years old and this is also the first time he is going full time to school in a new place. He is experiencing a number of changes. He is manifesting his feelings by ignoring me, being disrespectful and not wanting me to put him in bed and read a story to him. Now he only wants his daddy to be with him and not me. I am so sad! What is the right thing to do?
