Okay, so my little boy will be ready this Friday

...wooohooo!!! However, I'm a nervous wreck!!!

I think I've got all his things together and ready (I think!!). My mom will be taking care of him while I'm at work during the day. My biggest fear is that he bonds with her and not me!!!!

I have to be at work at 07:00 and I will be home for lunch at 13:00 then back home at 16:00 from Monday to Thursday and Friday's I'm home at 14:00. Do you think he'll forget me????

I'm SO nervous!! I've never had a puppy before so this is a BIG step for my boyfriend and I. We've puppy-proofed the apartment and even built him his own den with plenty of toys and so on where he'll spend most of his time. My mom will only be there for the first 2 - 3 weeks with him as he'll only be 7 weeks on Friday (I know, it's a bit young but the breeder said he's healthy and eating very well).
So, does anyone have any general tips or pointers for us????
I would really appreciate it!!!!
