My son will be nine months old in a week. We have an L-shaped living room, and the L is gated off as a play area. It's probably around 9'x9', so it's a decent size.

When I am sitting in his play area, he plays pretty independently. But if I step over the gate to do something else in the apartment, he melts down. And if I let him roam on the other side of the gate -- which I prefer not to do because it's not baby-proofed -- then he follows me around, pulls up on my leg (which renders me useless because I can't walk) and cries to be picked up.

I have no issue spending time with him and focusing on him. I understand that he's a baby and he wants his mommy. But is there any way I can stem this behavior? Sometimes I need to get other stuff done. This weekend I was trying to make a sandwich with him clinging to my leg. I have no idea how I will get my taxes done this year.

What is age-appropriate behavior, and how do I figure out when and how to set limits?

Please don't suggest baby wearing because my back is mess. So, that is not an option for me.
