maybe he'll stop sleeping in there when baby arrives because it disturbs him? Do you think it's because he's scared and that's why he comes in?
I have no idea! We have had many conversations with him about why he won't stay in his room. He always has a different reason, so I think he is making stuff up. I am thinking that we might put him in a different bedroom. We have a bedroom that is right beside ours, it has always been the baby's room because of it being so handy to me to nurse. But if it makes him feel better to be closer to us I will gladly move him to it!
