It has nothing to do with bonding after birth. He just doesnt see you enough now. He doesnt even remember who was there and wasnt the first week or 2 or even 3 weeks of birth. Relax he can sense your stress instead maybe you can take a day off and take him to the zoo and spend some time with him. Make sure your cooking dinner for him and feeding him dinner make sure he sees you in the morning. I know you have to work to provide for him but Is it possible the nanny can bring him to have lunch with you once in a while. She can drop him off and you can take him to McDonalds. Make sure your nanny is being excited with him when you are coming home from work, and speaks about you positive and exciting during the day. Have your nanny let your son call you during the day just so he can hear your voice. Your nanny needs to help you keep your relationship strong by making all these efforts. She sounds like a lovely nannny and be greatful for her dont sleep with him but establish a bed time that is special to the two of you maybe read his favorite book or tickle his back whatever works for you. Sleeping with you is more for you than him. Try not to feel guilty and if you can get your nanny to cooperate with the suggestions maybe it can help. Good Luck!
