my 5 years old son needs mom or dad to sleep

Hi,
My 5 years old son needs his dad or me to go to sleep. We have had a consistent bed routine since he was a baby; bath, book and sleep. When we tell him to try go to sleep on his own He gets upset . He wakes up during the night and calls for his dad so my husband has to go and see him, which results in my husband sleeping in his bed every night. We do not know what to do. We have also a 5 months old baby and we are afraid our son would feel rejected if we try a harder approach.
He has always been a sensitive boy and my husband is afraid of upset him. At the contrary, I think we should more determined and encourage him to learn to settle himself to sleep.
thank you for your time

I hope someone can help you.  I think that you need to figure out what you can do as soon as possible.  My 11 yr old still sleeps with me.  I have had a reguar routine her whole life, but nothing seems to work.  If I demand that she sleeps in her own bed I will wake up and find her in my bed.  It has gotten so bad she has asked to move her bed in my room.
