All I know is Jackson would never stand for being in another room away from me -- he would bark too. Jackson will often sleep in on weekends with me until 10am or later lol. It's worth him being in my bed.
I love him being in my room though and I honestly can't imagine him not sleeping with me. He's been in my bed since 12 weeks old. No issues. In the beginning, we obviously were getting up in the middle of the night still but by 6 months old, no way, he was fully potty trained.
