Well it's a good thing in my book Jim. I don't beleive in hauntings but do beleive in presence of people who have passed. You said your mom and you were very close and you do live in her old house. I wouldn't want to bring anyone in to scare it away. If it's your mom it's all good, she is a good ghost...couldn't think of a way to say that so it doesn't sound tacky. I've heard things like this before, and do beleive it can happen.
I think it happens in all kinds of ways, most of which a lot of people don't even really notice. An example here at my house. We had several people pass away right before my grandson was born. We were video taping him one day he was only a four months old. All of a sudden he turned to the door and stated smilling till he got to the point where he was laughing really hard. I went over to the door and he moved his head as to look by me and started up laughing again. My dad and my husband's dad had recently passed so I truly beleive it was one of them coming to see what would have been the first great-grandchild for both of them.
You have a lot more things happening but I do beleive it's just your Mom looking over her little boy. Being a father you know your kids grow up but they will always be your babies....
