Product recommendations needed!!!: What are some decent gates some of you mommies got? I have one baby gate that I got for my dog but it doesn't properly work in my doorways so it's pretty much pointless; since I live in an apartment I'm a little iffy on the gates that require mounting portions of it to the doorways, but those may be my only options, so I just wanted to know if any of you mommies have any particular gates you've liked using?
