Attachment

My son is a month old now.. Since the beginning he always wants to be with me which i love but when u need to do things it sucks... He will only sleep if he is laying on top of me. If i put him down he wakes up and cries... He will sleep on his belly at times but im scared to walk away of fall asleep with him like that... He literally will cry until i pick him up.. Instantly he calms down... I dont know what to do
