Anxiety over sleep

Cat ❤👣🍼 • I'm 23 years old. Married on 5.07.14 to my soulmate. First baby Nesbitt due in November❤🍼👣👶
My wee boy is a week and a bit old. He sleeps in his moses basket but me or my hubby is always with him. I feel scared putting him in it and going to sleep as I can't here him breathing. Hope that makes sense. Any tips on how to get past this? Or me and hubby will never be able to share a bed again. Thanks
