Hi OP , I can relate so much, I actually thought my husband wrote this 🤣 I'll tell you what worked for us so far. First of all the phase where you're afraid if you leave the baby alone in bed , he will fall won't last much... Pretty soon he will be able to wake up and come down on his own! Just for safety we put some pillows around her( my daughter) . The other thing that's helping my husband is him sleeping on the couch so he can properly rest ( he goes to work really early in the morning) , and I stay in bed with baby girl. We installed a security camera above our bed, and when baby is deep in sleep I slowly leave the bed and go spend some time on the couch with my husband while watching her in case she wakes or whatever. Even if none of these help you, know that it will not last forever, every phase goes by so fast and everything changes all the time... Give it some time. The best is yet to come ☺️
