Your baby may be lonely,he is used to sleeping with siblings. At some point he will give up or you can put him in a crate next to your bed (cover it) and you can atleast gently sush him without getting out of bed as much. How often puppys need to potty at night depends on the age. Keep telling yourself THIS IS A BABY,not a grown up. It is part of the training that will continue for the rest of his life.
Mine sleeps with me,this was a choise that I made for my baby and it isnt for everyone,but it is an option.
Good luck |
