How much is too much?

I made what I'm thinking is my last purchase for Christmas last night. It was a pretty large gift and a small gift. I have two already on their way here, and we have grandparents still sending their gifts. I don't know how much more baby stuff can physically fit in my 800ish square ft apartment. I've lived here for four years. It's a beautiful complex, but we need more space. I want Austin to enjoy his first Christmas he already has so many presents and toys just laying around. I guess I need help organizing his things until he has his own room. This place isn't big enough for the three of us. Plus he's starting to walk. He won't stay in one place long as it is. Im curious as to how many gifts would be considered enough for a single 10 month old baby. Right now he's looking at about 20 gifts plus his stocking, not including what others might get him. Sure it sounds good but physically 20 gifts as it is might take a little too much space.
